Answer:

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
