What is the probability of obtaining exactly seven heads in eight flips of a coin given that at least one is a head?
The probability of obtaining 7 heads in eight flips of a coin is:P(7H) = 8(1/2)8 = 0.03125 = 3.1%
If a number cube is rolled 4 times what is the probability that the same number is rolled at least twice?
It is 0.722... recurring.
A dice is rolled 12 times What is the probability of at least two 5's appearing?
The probability is 0.6187, approx.
If sixteen dice are rolled what is the probability of rolling at least one six?
It is 0.9459
What is the probability of tossing a coin 6 times and obtaining at least 3 consecutive heads?
The probability is 5/16.
If 3 dice were rolled 1000 times what is the probability of rolling a 14?
The probability that 14 is rolled at least once is 1 - 5.5*10-32 which, for all intents and purposes, can be treated as 1.
What is the probability of obtaining exactly two heads in three flips of a coin given that at least one is a head?
The probability of obtaining exactly two heads in three flips of a coin is 0.5x0.5x0.5 (for the probabilities) x3 (for the number of ways it could happen). This is 0.375. However, we are told that at least one is a head, so the probability that we got 3 tails was impossible. This probability is 0.53 or 0.125. To deduct this we need to divide the probability we have by 1-0.125 0.375/(1-0.125) = approximately 0.4286
A pair of dice are rolled find the probability at least one dice is a 4?
When rolling one die, the probability of getting a 4 is 1 in 6, or 0.1667. If two dice are rolled, you get two unrelated chances of rolling at least one 4, so the probability is 2 in 6, or 0.3333.
What is the probability of obtaining a sum of a least 4 when rolling a pair of dice?
11/12
What is the probability of obtaining at least one head when a coin is flipped four times?
The probability of obtaining 4 tails when a coin is flipped 4 times is: P(4T) = (1/2)4 = 1/16 = 0.0625 Then, the probability of obtaining at least 1 head when a coin is flipped 4 times is: P(at least 1 head) = 1 - 1/16 = 15/16 = 0.9375
What atmost means in probability?
all probabilities smaller than the given probability ("at most") all probabilities larger than the given probability ("at least")
What is the probability of rolling at least two sixes when a fair six sided die is rolled 5 times?
It is 0.1962
