If X is a random variable representing the number of children that end up having light-colored eyes, then X follows a binomial distribution with success probability p = 0.25 and number of trials n = 5.
The variance of a binomial distribution with these parameters is n p (1 - p), so the variance in this case would be
5 • 0.25 • (1 - 0.25) = 0.9375 ≈ 0.9
Step-by-step explanation:
I don't know the answer to this one so could someone please tell me
Thanks
The shaded part is AXY, so if you cut the rectangle into smaller parts you will see that AXY takes up 1/8 of the ABCD
