Question

Of the last 100 customers entering a computer shop, 25 have purchased a computer. If the classical method for computing probability is used, the probability that the next customer will purchase a computer is

a.0.25
b.0.50
c.1.00
d.0.75

Answer 1

correct option is b.0.50

Step-by-step explanation:

given data

computer shop = 100 customers

purchased computer = 25

solution

we know that past data does not affect the probability of next outcome

so when they buying computer or net

so here

probability of customer buy computer is =
`(1)/(2)` = 0.5

and

probability of customer not buy computer is =
`(1)/(2)` = 0.5

so here chance of buying as they buying or not buying is 50 %

so correct option is b.0.50
