Question

Based on surveys, 97% of students own cell phones. What is the probability that 10 randomly selected

students all own cell phones? Round your answer to 4 decimal places.

Answer 1

`Probability = 0.7374`

Explanation:

Given

Represent the probability that a student has a phone with p

`p = 97\%`

Required

Determine the probability that 10 has

This is calculated as thus:

`Probability = p^n`

Where n = 10

`Probability = (97\%)^(10)`

`Probability = 0.97^(10)`

`Probability = 0.73742412689`

`Probability = 0.7374` --- Approximated
