A pizza shop owner determines the number of pizzas that are delivered each day. Find the mean (expected value) for the distribution shown below.
Number of deliveries X 35 36 37 38 39
Probability P(X) 0.1 0.2 0.30 0.3 0.1
--------
Ans: 0.1*35 + 0.2*36 + 0.3*37 + 0.3*38 + 0.1*39
-------
= (1*36 + 2*36 + 3*37 + 3*38 + 1*39)/10
-------
= 37.2
