Question

question 9 of 10
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 80%. which of these
groups of numbers could represent a success?
a. 0, 1, 2, 3, 4, 5, 6, 7
b. 0, 1, 2, 3, 4, 5, 6, 7, 8
c. 0, 1, 2, 3, 4, 5, 6
d. 0, 1, 2, 3, 4, 5

Explanation:

Step1: Calculate the number of successful numbers

Since there are 10 numbers (0 - 9), and the probability of success is 80% = 0.8. The number of successful numbers \(n=10\times0.8 = 8\)

Step2: Check each option

• Option A: The set \(0,1,2,3,4,5,6,7\) has 8 numbers.
• Option B: The set \(0,1,2,3,4,5,6,7,8\) has 9 numbers.
• Option C: The set \(0,1,2,3,4,5,6\) has 7 numbers.
• Option D: The set \(0,1,2,3,4,5\) has 6 numbers.

Answer:

A. \(0,1,2,3,4,5,6,7\)
