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

Answer:

$Probability = 0.7374$

Step-by-step 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
