The dimensions of a square are 50 feet X
50 feet. Find the total area of the square.

2500 square feet

Step-by-step explanation:

We know that the area of a square is = a*a

here a= 50 feet

area= 50*50

=2500 square feet.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
