Answer:
1/3
Step-by-step explanation:
21.
Probability of an even happening is equal to the number of desired outcomes divided by the total number of outcomes.
The desired outcomes here are 3 and 9. There are two desired outcomes.
The total number of outcomes is 6.
p(event) = (number of desired outcomes)/(total number of outcomes)
p(3 or 9) = 2/6 = 1/3
