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 rolling a five? Round to the nearest whole percent if necessary.

A) 83%
B) 93%
C) 7%
D) 17%

Answer 1

The Answer is A. 83%

Explanation:

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
