a.) The possible outcomes of a cube roll are 1, 2, 3, 4, 5, 6. So the odd outcomes out of these are 1, 3, 5.
That means the theoretical probability of rolling an odd number
= No. of favorable outcomes in which we get an odd number/Total no. of outcomes
= 3/6
= 0.5
b.) From her experiment of 500 rolls, Ashley observed the outcome 1 - 93 times, outcome 3 - 62 times, and outcome 5 - 86 times.
So, the experimental probability of rolling an odd number = (93 + 62 + 86) / 500 = 0.482
c.) The larger the number of rolls, the greater the likelihood that the experimental probability will be close to the theoretical probability.
