Consider a binomial random variable with n = 6 and p = 0.7. Let x be the number of successes in the sample. Evaluate the probability. (Round your answer to three decimal places.) P(x = 3)
Added by Brendan K.
Step 1
This is calculated as C(n, x) = n! / [x!(n-x)!], where "!" denotes factorial. So, C(6, 3) = 6! / [3!(6-3)!] = (6*5*4) / (3*2*1) = 20. Show more…
