Question

1. Find P(rolling 2 or 5) with one number cube.

Answer 1

`(1)/(3)`

Explanation:

A fair dice has 6 outcomes, 1, 2, 3, 4, 5, 6.

The outcomes 2 and 5 are 2 outcomes out of total 6 outcomes.

`(2)/(6)=(1)/(3)`

Answer 2

1/3

Explanation:

There are 6 possible outcomes when rolling 1 die

1,2,3,4,5,6

There are 2 outcomes that fit the category of 2 or a 5

P ( rolling 2 or a 5) = number of 2's or 5's / total number of outcomes

= 2/6

=1/3
