Question

A​ 12-sided solid has faces numbered 1 to 12. The table shows the results of rolling the solid 200 times. Find the experimental probability of rolling a number less than 3 .

Answer 1

3/20 or 0.15 or 15%

Explanation:

The experimental probability is

amount of wanted outcomes/total amount of outcomes

Less than 3 is 1 and 2.

1= 14 times

2= 16 times.

Add, get 30.

30 is the amount of wanted outcomes, and the total is 200.

30/200 is either 3/20, 0.15, or 15%, because of different formats.
