A car salesman sends updates to customers via text. The probability model describes the number of text messages the salesman may send in a day.

Texts Sent 0 1 2 3 4 5
P(X) 0.05 0.05 0.1 0.1 0.4 0.3

How many texts would you expect the salesman to send each day?
3.9
3.65
3.25
2.9
2.45

Respuesta :

According to the discrete distribution given, the salesman is expected to send 3.65 texts each day.

What is the expected value of a discrete distribution?

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.

Considering the discrete distribution given in the model, we have that:

E(X) = 0.05(0) + 0.05(1) + 0.1(2) + 0.1(3) + 0.4(4) + 0.3(5) = 3.65

The salesman is expected to send 3.65 texts each day.
