Question

find the probability that a number selected at random from the numbers 1-25 is not prime number when each of the given number is equally likely to be selected plz answer fast and explain each step plz answer

Answer 1

favourable out comes ={1,4,6,8,9,10,12,14,15,16,18,20,21,22,24,25}
Number of favourable outcomes=16
number of total possible outcomes=25
p(not a prime)=(number of favourable outcomes)/number of total possible outcomes
=16/25

Answer 2

Answer:

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25

no. of non primes =16

total numbers=25

the probability of getting a non prime = 16/25

                    ANSWER=16/25
