What is the probability of getting a head or a 4?

When a coin is flipped and a die is thrown, what is the probability of getting a heads or a 4 ? But the right answer is 712.

What is the probability of getting 4 or 5 heads?

Because, if we toss a coin, then there are two possible outcomes either we get a head or a tail. Thus, the probability of getting 4 or 5 heads out of the 10-coin tosses is 0.451.

What is the probability of getting heads then a number less than 4?

Explanation: To get a number less than 4 on a die, 3/6 is the probability. To get a heads is a 1/2 chance. So, since both events are independent, multiply the two probabilities together to get your answer.

What is the chance of either getting all heads or no heads in 4 tosses?

Answer: If you flip a coin 4 times, the probability of getting all heads is 1/16.

What is the probability of getting a head on a coin or getting a 4 on a die?

The probability of not getting a head on the flip of a coin is 1/2. The probability of not getting a 4 is 5/6 and so the probability of getting neither a head or a 4 is 1/2 x 5/6 = 5/12 and so the probability of getting a 4 or a head is 1 - 5/12 = 7/12.

What Is the Probability of Getting Heads Four Times? : Math Tutorials

What is the probability of getting 4 heads in 10 tosses of a fair coin?

Suppose we toss a single coin, the probability of getting heads is equal to 0.5. The reason is that if we toss a coin, then there are only two possible outcomes: either we can get heads or tails. Thus, the probability of getting exactly 4 heads out of the 10 coin tosses is P(X=4)=0. 205.

How many heads are there when 4 coins are tossed?

probability of getting heads in toss of 4 coins=4(21)=2.

What is the probability of getting either two or four from the throw of a dice?

probability of getting 2 or 4 is 61+61=62=31.

What is the probability of getting more heads than tails on four tosses of a fair coin?

The probability of having more heads than tails is 5/16: HHHH, HHHT, HHTH, HTHH, THHH. I realize that I can count it and that four of these results have H first, meaning that the answer is 4/16 or 1/4.

What is the probability that heads occur at least 4 times when a coin is tossed 5 times?

Detailed Solution

Combination formula ⁿC_r = n!/(n – r)! r! At least 4 heads implies that one can get either 4 heads or 5 heads. ∴ The probability of getting at least 4 heads is 3/16.

What is the probability of getting 2 or 3 head?

Another way to get to 1/8 is to say that each coin has 2 possible outcomes, so 3 coins have 2^3 or 8 possible outcomes. Only one of these is all heads, so again 1/8.

What is the probability of getting a 4?

The probability of getting a 4 when a die is rolled is 1/6.

What is the probability of getting 1 or 2 heads?

The probability of heads on the first toss is 50%, just as it is on all subsequent tosses of the coin. The two outcomes of the toss of a coin are heads or tails. For any individual toss of the coin, the outcome will be either heads or tails.

What is the probability of getting 3 or 4?

So the probability of getting either 3 or 4 is =62=31.

What is the probability of getting 4 or lower?

To get a number less than 4 on a die, 3/6 is the probability.

What is the probability of getting 4 heads or 4 tails when a fair coin is tossed 4 times?

Answer and Explanation: or 6.25%. Note that this is also the probability of getting any particular sequence of 4 tosses (e.g. HTHT, TTHH, etc).

What is the probability of getting at most 4 tails?

Solution: Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. Therefore, the probability of getting tails 4 times in a row is 1/16.

What is the probability of getting two or more heads when a coin is tossed four times?

There are ×4=16 possible results: 4C2=6 of them have 2 heads. Since all 16 are equally likely, the chance is 166=83.

What is the probability of getting two heads and tails when 4 coins are tossed?

The favourable outcomes for the event are HHTT, HTHT, HTTH, THHT, THTH and TTHH. That's 6 out of 16 outcomes. Hence, the probability is 616 = 38.

What is the probability of rolling a 4 or 6?

Summary: The probability of rolling a '4' or a '6' on one toss of a standard six-sided die is 1/3.

What is the probability to roll a total of 4 on the two dice or a total of 11?

Answer: The probability of rolling two dice and getting a sum of 4 is 1/12. Let's find how likely we get a sum of 4 when we roll two dice simultaneously. So, when we roll two dice there are 6 × 6 = 36 possibilities. When we roll two dice, the possibility of getting number 4 is (1, 3), (2, 2), and (3, 1).

What is the probability that the sum of two dice rolls will yield a 4 or 6?

Hence, the probability of getting a sum of 4 or 6 is 8/36, or 2/9, as desired.

What is the probability of 4 heads when you toss a coin 7 times?

Probability as requested = 35/128 = 0.2734375 ~ 27.3%. 35 : (128–35), or 35 : 93, which is to say: 35 ways to get exactly 4H and 93 ways to not get exactly 4H.

What is the formula for probability?

Probability determines the likelihood of an event occurring: P(A) = f / N.

How to calculate probability?

You can use the following steps to calculate the probability of an event: Step 1: Identify an event with one result. Step 2: Identify the total number of results or outcomes and favourable outcomes that can occur. Step 3: Divide the number of favourable outcomes by the total number of possible outcomes.
