Question

an integer is chosen between 30 and 100. Find the probability of getting a) a perfect square integer b) an integer which is a multiple of 2 and 5 both​

Answer 1

Answer:

a):- 1/7

b):- 4/35

Step-by-step explanation:

a:- square root between 30-100=10

total number between 30-100=70

Hence, p(square root between 30-100=10/70

=1/7

b:- integer which is a multiple of 2 and 5 both between 30-100=8

total number=70

Hence, p(integer which is a multiple of 2 and 5 both between 30-100)=8/70=4/75
