Question

Suppose that a randomly generated list of numbers from 0 to 9 is being used to simulate an event that has a probability of success of 40%. Which of these groups of numbers could represent a success?

A. 0,1
B. 0,1,2,3
C. 0,1,2
D. 0,1,2,3,4

Answer 1

B. 0, 1, 2, 3

Explanation:

You want to know the numbers from 0–9 that could be used to represent success if the probability of success is 40%.

Model

To model a 40% success rate, we want 40% of the possible outcomes to represent success. There are 10 numbers in the range 0–9, so we need to have 40%×10 = 4 of the numbers represent success.

A suitable choice for 4 of the numbers is ...

0, 1, 2, 3 . . . . . choice B
