Answer 1

The expected value for the number of cups is 1.881 cups

The formula for the expected value is :

• ∑(X * P(X))

Taking the product of each pair :

(0 * 0.024) = 0

(1 * 0.423) = 0.423

(2 * 0.291) = 0.582

(3 * 0.172) = 0.516

(4 * 0.090) = 0.360

Taking the sum ;

(0 + 0.423 + 0.582 + 0.516 + 0.360)

= 1.881

The expected value for the number of cups is 1.881 cups.
