Question

There are
26
participants at a conference, each with a unique ID from 1 to
26
. One of them at random is chosen for an award. What is the probability that the award goes to a participant whose ID is a prime number?

Answer 1

prime no between 1 to 26 is 9(2,3,5,7,11,13,17,19,23) no. of a=9 therefore probability of no.is 9/26

Answer 2

here's your answer...

the no.of participants= 26
every person has their unique ID from 1-26
the probability that the award goes to a participant whose ID is a prime number= X
the prime no.s from 1-26 are :
2,3,5,7,11,13,17,19,23.
there are 9 prime no.s
So,
your answer = no.of possible outcomes/ total no.of outcomes
this is the formula
answer= 9/26
the probability is unlike...
