Question

PLATO

A six-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. In the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times.

The experimental probability of rolling a 3 is %, which is approximately % more than its theoretical probability. (Round off your answers to the nearest integer.)

Answer 1

StepLet's right out the amount of times out of 20 the number 3 came out for all trials:

6/20 , 6/20, 5/20, 7/20

This probability averages at: 6/20 (6 + 6 + 5 + 7 /4 ) = 0.3

The normal probability to get one number is = 0.1666 recurring (1/6)

In relation to the normal probability the probability of getting a 3 on this die is almost double.

The experimental probability consistent with this simulation is: 6/20 (0.3)

Answer 2

The experimental probability of rolling a 3 is 30%, which is approximately 13% more than its theoretical probability.
