Question

A cube is rolled 2 times in a row. What is the probability of rolling a number greater than 2 both times

Answer 1

2/3

Explanation:

greater than 2: 3, 4, 5, and 6

4/6=2/3

Answer 2

`(4)/(9)`

Explanation:

we need to get one of this set {3,4,5,6} out of {1,2,3,4,5,6} each time

then

the probability of rolling a number greater than 2 both times =

`(4)/(6) *(4)/(6) =(2)/(3) *(2)/(3) =(4)/(9)`
