Problem 2E

Let and be independent random variables with respective binomial distributions b(3, 1/2) and b(5, 1/2). Determine

(a) P( = 2, = 4).

(b) P( + = 7).

Step by Step Solution

Step 1 of 3

It is given that X1 and X2 are independent events with binomial distribution b (3, 1/2) and b (5, 1/2).

Apply the binomial distribution, to find the probability. (a) The probability of  Substitute the values of probability of X equals 2 and 4. Thus, the probability of , 0.05859.
