Answer:
42
Step-by-step explanation:
Given that:
Sample space = {1, 2, 3, 4, 5,6}
Probability of obtaining an odd number in a single roll :
Probability = required outcome / Total possible outcomes
Required outcome = {1,3,5} = 3
Total possible outcomes = 6
P(odd number) = 3/6 = 1/2
Number of odds on 84 die rolls :
1/2 * 84 = 42 times
