You are asked to find the error. The error is that 4,100,000 is the answer to 4.1×10^6, not 4.1×10^-6. The correct answer to 4.1×10^-6 is 1/4,100,000.

Mrac [35]

Answer:

E(X) = 17.4

Step-by-step explanation:

We can calculate the expected value of a random X variable that is discrete (X takes specific values ) as:

E(X) = ∑xp(x) where x are the specific values of x and p(x) the probability associated with this x value.

In this way the expexted value is

E(X) = ∑xp(x) =(16*0.6)+(18*0.3)+(20*0.2) = 8+5.4+4 = 17.4
