Question 7 • Algebra 2 with Probability

A computer’s random number generator produces random integers from 1 to 50 What is the probability that the first 3 integers generated are single-digit numbers?

Answer
A
0 point 5 1 2 0
B
0 point 0 0 8 0
C
0 point 5 5 1 4
D
0 point 0 0 5 8

Explanation

The single-digit integers from 1 to 50 are 1 through 9, so the probability for one generated integer is 9/50. The three generations are independent, so the probability all three are single-digit is (9/50)³ = 729/125000 = 0.005832. Rounded to four decimal places, this is 0.0058, the choice stating 0 point 0 0 5 8.
