Consider the probability distribution shown below. X 0 1 2

P (X) 0.25 0.60 0.15

A) Compute the expected value of distribution.

B) Compute the standard deviation of the distribution. ( Round four decimals).

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.
