Answer 2

Step-by-step explanation:

total no of two digit numbers = 90

a) How many multiplies of 5 are there in the

box?

10, 15, 20, 25, ...........95--------> 18 Numbers

b) what is the probability of getting a multiple

of 5?

P(A) = (numbers divisible by 5)/ (total no of two digit numbers)

18/90= 1/5

c) what is the probability of not getting a multiple of 5?

not a multiple of 5 = 90-18 = 72

probability of not getting a multiple of 5

= 72/90

=4/5
