Answer:
13/100
Step-by-step explanation:
we know that
The probability of the event occurring plus the probability of the event not occurring must equal to 1
If the probability that a pupil in a class has a calculator is 0.87
then
The probability that the pupil does not have a calculator is equal to
[tex]1-0.87=0.13[/tex]
Convert to fraction
[tex]0.13=\frac{13}{100}[/tex]
