Answer:

[tex]Probability = 0.7374[/tex]

Step-by-step explanation:

Given

Represent the probability that a student has a phone with p

[tex]p = 97\%[/tex]

Required

Determine the probability that 10 has

This is calculated as thus:

[tex]Probability = p^n[/tex]

Where n = 10

[tex]Probability = (97\%)^{10}[/tex]

[tex]Probability = 0.97^{10}[/tex]

[tex]Probability = 0.73742412689[/tex]

[tex]Probability = 0.7374[/tex] --- Approximated
