Question

A six-sided number cube is rolled 350 times and the results are recorded as follows: 58 ones, 63 twos, 52 threes, 61 fours, 60 fives, and 56 sixes. what is the experimental probability of not rolling a five? round to the nearest whole percent if necessary.

Answer 1

The Probability a certain Event = 1 - Probability of that certain event not to happen

According to this, it is true that:

Probability (not rolling 5)=1- P(rolling 5)=
`1- (60)/(350)= 1- (6)/(35)=(35-6)/(35)= (29)/(35)=0.83`


Answer: P(not rolling 5)=83%
