The probability that the number of successes is exactly 0

Question

assume that a procedure yields a binomial distribmutinous with 3 trials and a probability of success of 0.10. Use a binomial table to find the probability that the number of successes is exactly 0.

 

the answer I got was 0.2 but I says I am incorrect I don't know what I am doing incorrect

Answer 1

Your probability of success (p) is 0.1, your number of trials (n) is 3, and your number of successes (X) is exactly 0.

 

In a binomial table, your p is at the top, your n is at the far left and the X for each n is to the right of n

 

For p = 0.1, n = 3, and X = 0, the probability is 0.729
