A 10

Question:

The probability of rolling a number less than 3 on a number cube is 2/6 . Jennifer rolls a number cube 60 times. How many times should Jennifer expect to roll a number less than 3?

The expected value is 20

Step-by-step explanation:

Given

--- Number of rolls

-- probability

Required

Determine the expected value

Expected value (E(x)) is calculated using:

Substitute values for n and p

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
