What is the probability of obtaining at most one head if a coin is tossed three times?
87.5\%
If you flip a coin three times the chance of getting at least one head is 87.5\%.
What is the probability of getting at most 6 heads?
21/128
When a coin is tossed 9 times the probability of getting exactly six heads is obtained with the help of Bernoulli trials. The probability of getting exactly six heads is 21/128.
How do I find the most at one head?
At most one head means number of heads can be 0 or 1. At least one head means the number of head is greater than or equal to 1. b) atmost one head. The possible outcomes are,TTT, THT, TTH, THH, HHT, HTH, HHH, HTT (8).
What is the probability that a number selected from 1 to 15 is a multiple of 4?
From the given 15 numbers, the numbers that are multiple of 4 are 4,8 and 12. Therefore, Probability that a number selected is a multiple of 4 =315=15. Hence, 15 is the probability that a number selected from the numbers 1,2,3, ……,15 is a multiple of 4.
What is the probability of getting exactly 2 heads when a coin is tossed 3 times?
1/2
Answer: If you flip a coin 3 times, the probability of getting at least 2 heads is 1/2.
What is the probability of getting at most 1 head if you toss the coin twice?
Originally Answered: tossing a coin twice what is the probability of getting at most one head? The answer is 3/4, as explained in other answers.
What is the probability of getting all heads with 4 tosses?
If You Toss A Coin 4 Times What Is The Probability Of Getting All Heads June 1, 2021 by Admin 1/16 The probability is therefore 1/16. N= 4: There is only one possible outcome that gives 4 heads, namely when each flip results in a head.
What is the probability of getting all heads on a coin?
Furthermore, What is the probability of getting all heads?, The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
What is the probability of getting 3 heads in a row?
The probability of getting a heads first is 1/2. The probability of getting 2 heads in a row is 1/2 of that, or 1/ 4. The probability of getting 3 heads in a row is 1/2 of that, or 1/8.
What is the probability of two out of four possible outcomes?
But it’s up to you, and in some situations you really can’t avoid considering outcomes with differing probabilities. Two out of four qualify, so the probability is 1 / 2. Thanks for contributing an answer to Mathematics Stack Exchange!
