Ivenika [448]

Answer:

The expected number of new claims filed each day is 1.8.

Step-by-step explanation:

We are given the following probability distribution:

$P(X = 0) = 0.25$

$P(X = 1) = 0.15$

$P(X = 2) = 0.25$

$P(X = 3) = 0.25$

$P(X = 4) = 0.1$

a. What is the expected number of new claims filed each day

Multiplication of each outcome by its probability, so:

$E(X) = 0*0.25 + 1*0.15 + 2*0.25 + 3*0.25 + 4*0.1 = 1.8$

The expected number of new claims filed each day is 1.8.
