Question

A number cube is rolled 360 times and the results are recorded as follows: 41 ones, 54 twos, 62 threes, 75 fours, 33 fives, and 95 sixes. What is the experimental probability of rolling a two or a three?

Answer 1

There is an equal odd of rolling any of the parts of a dice. So the ratio per side would be 1:6, only because every side has the same probability to be shown.

Answer 2

P(3's) =62/360 = 31/180 = 0.17

P(2's) = 54/360 = 3/20 =0.15

P93's) or P(2's) = 0.17 + 0.15 = 0.32 or 32%
