Question

A number cube was rolled 50 times. The results are shown in the table.

Number Frequency
1 3
2 6
3 17
4 11
5 4
6 6

What is the experimental probability of rolling a 2 or 3?
A. 6/50
B. 17/50
C. 23/50
D. 27/50

Answer 1

The answe is D i believe.

Answer 2

The experimental probability of rolling a 2 or 3 can be found by adding the frequency of rolling a 2 to the frequency of rolling a 3, and then dividing by the total number of rolls:

Experimental probability = (frequency of 2 + frequency of 3) / total number of rolls
Experimental probability
the answer is (C) 23/50
