Question

what is the probability of getting a composite number from 51 to 100​

Answer 1

p of getting composit number between 51 and 100

total composite numbers =52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100

total numbers are 49

p(of getting composite number)= 39/49 (divide on your own)

hope it helps

Answer 2

The composite numbers between 51 to 100 are

52,54,55,56,72,

94,95,96,98,99

There are composite numbers

P(E)=No.of Favourable outcomes/total no .of outcome

No.of favoirable outcomes=10

Total no.of outcomes=50

The probability of getting composite numbers =10/50

=1/5
