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? 
A. 0.32
B. 0.18
C. 0.07
D. 0.68

anonymous · Answer

The experimental probability of rolling a two or three would be equal to the total number of twos plus the total number of threes, divided by the total number of rolls. There are 41 ones, 54 twos, and 360 total rolls. So the probability would be
(41+54)/360
