Q. If you roll a 6-sided die 12 times, what is the best prediction possible for the number of times you will roll a five?____ times
Understand Probability: Understand the probability of rolling a five on a 6-sided die. Each side of the die has an equal chance of landing, so the probability of rolling a five is 1 out of 6. Calculation: P(rolling a five)=61
Calculate Expected Number: Calculate the expected number of times to roll a five in 12 rolls.Using the probability from Step 1, multiply it by the total number of rolls.Calculation: Expected number of fives = 61×12=2
