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
