Question

what is the probability that a number selected from the number 1,2,3..........25 is a prime number is equally liked to selected​

Answer 1

Answer:

Step-by-step explanation:

S=(1,2,3,4,5,...,25)

nS=25

let A be the event that the probability that a no selected is a prime no. is

A=(1,2,3,5,7,11,13,17,19,23)

nA=10

therefore P(A)=nS/nA

                       =25/10

                       =5/2

ANS:5/2
