Simulation Situation

APCSP-EPETNP

Consider the program below:

count ← 0
REPEAT (365*10) TIMES
{
    if RANDOM (1,1000) <= 15
    {
        countcount + 1 
    }
}
DISPLAY (count)

The program above could be used to test which of the following?

A

The Chicago Cubs have a 1.5% chance of winning the World Series in any given year. This program would test the likelihood that the Cubs will win the World Series in the next decade.

B

A car has a 1.5% chance of not starting on any given morning. This program would estimate the number of times the car will not start in the next decade.

C

A national coffee chain estimates 1.5% of their customers visit more than once a day. This program would estimated the number of same-day repeat customers this coffee chain expects to see in the next decade.

D

A teacher estimates that 1.5% of students fail introductory computer science each term. This program would estimate the number of failures the teacher will have in the next decade.
