A binomial experiment is conducted with the given parameters. Compute the probability of X successes in the n independent trials of the experiment. In this case, n = 20, P = 0.9, and X = 18. Therefore, we need to calculate P(18).
Added by Andrew D.
Step 1
In this case, we have n=20, p=0.9, and we want to find the probability of X=18 successes: P(X=18) = (20 choose 18) * 0.9^18 * 0.1^2 To compute the binomial coefficient, we can use the formula: (n choose k) = n! / (k! * (n-k)!) where ! denotes the factorial Show more…
