if you roll a 6 - sided die 72 times, what is the best prediction possible for the number of times you will roll a five? times
Answer
Answer:
12
Explanation:
Step1: Determine probability of rolling 5
The probability of rolling a 5 on a 6 - sided die is $P(5)=\frac{1}{6}$.
Step2: Calculate expected number of 5s
Multiply the probability by the number of rolls. So, $\frac{1}{6}\times72 = 12$.
