Question

A number cube is rolled 10 times. An even number comes up 6 times. What is the experimental probability of an even number coming up? A.1/2 B.3/5 C.1/10 D.0

Answer 1

B

Explanation:

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.

A number cube is rolled 10 times, so

Number of trials or times the activity is performed = 10.

An even number comes up 6 times, so

Number of times an event occurs = 6.

Hence, the experimental probability is

`P=(6)/(10)=(3)/(5).`
