If the die is rolled times, how many times would you predict a roll of a or a ?
Find probability of getting or a , if the die is rolled times.
The ratio of the number of favorable outcomes to the total number of outcomes of an event is called Probability.
.
Possible outcomes
Total outcomes
favorable outcomes
Number of favorable outcomes
So,
Probability of getting a or a is .
The die is rolled times, So multiply probability by .
Therefore, the probability of getting or a , if the die is rolled times is .
