Question

A bag contains 30 tickets numbered from 1 to 30 .One ticket is selected at random .find the probability that the number is either odd or the square of an integer​

Answer 1

Answer:

total no.of tickects=30

odd numbers 15=>>15/30

square of an integer 5( such as 1,4,9,16,25)=>>5/30

=(15/30)+(5/30) (either case)

=(15+5)/30(lcm)

=20/30

=2/3
