A random variable follows a binomial distribution with a probability of success equal to 0.62. For a sample size of n=7 Find the probability of exactly 7 successes Answer: P (x=7)=
Added by Kayla F.
Step 1
62, and the sample size is n=7. We want to find the probability of exactly 7 successes, which means all 7 trials are successful. Using the binomial probability formula, we have: P(x=7) = (n choose x) * p^x * (1-p)^(n-x) where (n choose x) is the binomial Show more…

Consider a binomial random variable with n = 7 and p = 0.6. Let x be the number of successes in the sample. Evaluate the probability. (Round your answer to three decimal places.) P(x ≥ 3)
