Question

Sean recorded everyone’s number-cube rolls during the game.

Answer 1

Answer:

See below. Sean is in error.

Step-by-step explanation:

There are a total of 15 rolls of the cube.

If we count the number of  1's that are rolled we get  5 which is more than any other number. So the EXPERIMENTAL probability of getting a 1 is 5/15 = 1/3.

But this is NOT the THEORETICAL probability.

If we assume that it is a fair cube then the theoretical probability of a 1  is 1/6.

Each number has an equal theoretical probability of 1/6.

Answer 2

Answer:

Sean’s error is that he just looked the number of times 1 occurred. The theoretical probability of rolling a 1 is found by dividing the number of desired outcomes by the total number of outcomes. The correct probability of rolling a one is 1/6.
