Answer:

0.25

Step-by-step explanation:

Given that a recently married couple are planning to have four children. They are equally likely to have a boy as well as a girl.

Let X be the no of boys the couples have. X has two outcomes with p = 0.5

X is binomial with n = no of trials = 4 and p =0.5

the probability that they will have three boys and one girl

= $P(X=3)\\=4C3(0.5)^3(0.5)\\= 0.25$

Reqd prob = 0.25

Step-by-step explanation:

F(x) = (x + 7)³

= 3C0 * x³ + 3C1 * x² * 7 + 3C2 * x * 7² + 3C3 * 7³

= x³ + 21x² + 147x + 343.
