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

Answer:
1.36
Step-by-step explanation:
You are finding area. The equation for area is length x width = area.
The length is 1.7 m
The width is .8 m
A = 1.7 x .8
A = 1.36
207 cm^2
Im assuming this is a right triangle.
In that case, the formula is A=1/2bh
So 1/2(18)(23)= 207 :D
