Let X~bin(7,0.57), then P(X=2) is equal to a 0.1 b 0.3251 c 0.2341 d 0.2011 e 0.0278
Added by Colleen H.
Step 1
Since X follows a binomial distribution with parameters n = 7 and p = 0.57, we can write the probability mass function (PMF) as: P(X = k) = C(n, k) * p^k * (1-p)^(n-k) where C(n, k) is the number of combinations of n items taken k at a time. Now, we want to Show more…
