Question

5. Sam rolled a standard number cube 20 times. He rolled a five 6 times. What is the experimental probability of rolling a 5 based on Sam’s experiment? Give answer as a simplified fraction.

Answer 1

Sam rolled a standard number cube 20 times. He rolled a five 6 times.

Experimental probability is the number of times the event occurs divide by total number of trials.

He rolled a five 6 times. so number of times the event occurs is 6.

Sam rolled a cube 20 times. So the total number of trials is 20.

Experimental probability =
`(6)/(20) = (3)/(10)`

Answer is
`(3)/(10)`

Answer 2

The experimental probability is 3/10.

He rolled a 5 6 times out of 20 rolls, so the probability is 6/20, which simplifies to 3/10.
