Question

According to a baseball player's on base percentages, he gets a single 60% of the time, a double 25% of the time, a triple 10% of the time, and a home run 5% of the time. Which if these is a simulation using a random number generator to predict his next 20 on base results?

A: Single: 1-12; Double: 13-16; Triple: 17-19; Homerun: 20

B: Single: 1-12; Double: 13-17; Triple: 18-19; Homerun: 20

C: Single: 1-5; Double: 6-10; Triple: 11-15; Homerun: 16-20

D: Single: 1-10; Double: 11-15; Triple: 16-18; Homerun: 19-20

Answer 1

I know it's not C btw

Answer 2

Since the values are given in percents, we could generate the integers 1-100 and let 1-60 represent a single, 61-85 represent a double, 86-95 represent a triple, and 96-100 represent a home run. Simply use the first 60 to represent 60%, the next 25, or 61-85, to represent 25%, and so on. We could also divide all of these values by 5 and generate the integers 1-20.
Do 20 trials and record the results in a frequency table.

Answer 3

so now Divide each frequency by 20 to get the corresponding probability.

Answer 4

wait I'm confused-since the closest options only show 1-12 for the single, and not 13

Answer 5

Looking at the frequency table, the closest match seems to be Option B, so I guess that's my answer
