Question

There are tokens numbered from 1 to 30 in abox .one token is taken out of it at random.what is the probability the token taken out is (an even number) (a multiple of 5)a prime number

Answer 1

HeYA!!
--------


Probability of an Event P ( E ) = No. Of Favourable Outcomes / Total Number of Outcomes

Here , Total possible Outcomes = 30


A. ] P ( Even Number ). = 15 / 30

= 1 / 2



B]. P ( A Multiple of five ) = 6 / 30

= 1 / 5

C. ] P ( A prime Number )

= 10 / 30

= 1/3
