Answer 1

The probability of getting a 3 on each die is
`(1)/(3)`

Explanation:

Step one

The sample space for tossing two dice is 12

i.e the first die={1,2,3,4,5,6}= 6

and the second die = {1,2,3,4,5,6}= 6

making a total of 12 sample spaces.

Step two

Hence the probability of getting a 3 on each side is

pr(3 on each side) =
`(1)/(6) +(1)/(6)`

pr(3 on each side) =
`(1+1)/(6)` =
`(2)/(6) = (1)/(3)`

pr(3 on each side) =
`(1)/(3)`
