Question

How do we " find p (rolling 2 or 5) with one number cube?"

Answer 1

cube has 6 sides..

so chances of getting 2 = 1/6 as you have only one 2
similarly, getting 5 =1/6

so, (1/6) * (1/6) = 1/36..

Answer 2

@ganpat the question is 2 OR 5, not 2 then a 5, the chances are 2/6, reduce that to 1/3

Answer 3

oh sorry, it should be (1/6) + (1/6) = 2/6 = 1/3...
