Neil tossed a 6-sided die 90 times. The

results of his tosses are recorded in the

table below: If Neil tossed the die 135

times, predict the experimental probability

of rolling the number 3? (hint:set up a

proportion)

Number. Time Tossed

1. 13

2. 15

3. 14

4. 12

5. 18

6. 18

21

Step-by-step explanation:

Let's first get the probability that he had in rolling a 3 when he rolled the die 90 times. The formula for probability is times he got a 3 / times he rolled the die.

He got a 3 14 times, and he rolled 90 times, so the proportion is 14/90.

If we want to extend this proportion to when he rolls 135 times, we just multiply.

135 * 14/90 = 21 expected times he rolls a 3

Your answer should be the last one which is 18
