In a pizza hut, the following distribution is found for the daily demand of pizzas. Then expected daily demand and variance are respectively

Options

  1. A7.28 and 1.52
  2. B1.52 and 7.28
  3. C7.28 and 54.52
  4. D7.28 and 53

Correct answer

A. 7.28 and 1.52

Step-by-step solution

Mean = P_i x_i=7.28 and variance = P _ i x _ i ^2 - ( P _ i x _ i )^2=54.52-53=1.52
