Question

the probability that a pupil in a class has a calculator is 0.87. what is the probability that the pupil does not have a calculator? in a fraction?

Answer 1

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

$1-0.87=0.13$

Convert to fraction

$0.13=\frac{13}{100}$
