On any given day, a salesman can earn $0 with a 45% probability, $250 with a 25% probability, or $400 with a 30% probability. his expected earnings equal: $ nothing (round your answer to the nearest penny).

$ 182.5

Step-by-step explanation:

The expected value of occurring events having probabilities is given by :-

Given : On any given day, a salesman can earn $0 with a 45% probability, $250 with a 25% probability, or $400 with a 30% probability.

i.e. Probability of earning $0 = 0.45

Probability of earning $250=0.25

Probability of earning $400=0.30

Then , the expected earnings is given by :-

Hence, the his expected earnings is $182.5.
