Please show work

Answer 1

Answer: 6 times.

A fair number cube has 6 sides, therefore embodying the numbers 1-6.

There are 3 even numbers in 6.
There are 2 numbers that are greater than ‘2’ and even.

The proportional probability for rolling an even number greater than 2 per roll is 2/6, or 1/3.

Multiply 18 (number of rolls) by 1/3 = 6.

Answer 2

answer:
6 times

Explanation:
cubes have 6 faces, 3 of those being even and 2 of those being even and over 2
that gives a chance of 2/6 or 1/3
if he rolls it 18 times multiply the chances
1/3 • 18/1
18/3
6
