What is the probability of the event that a number chosen from 1 to 50 is prime number?

What is the probability of getting prime numbers between 1 to 30?

Prime numbers between 1 and 30 are 2 , 3 , 5 , 7 , 11 , 13 , 17 , 19 , 23 and 29. i.e. 10 / 30 = 1 / 3 . Hence , option (c) 1/3 is correct.

What is the probability of the event that a number chosen from 1 to 100 is a prime number *?

What is the probability of a ticket being drawn from a box?

Tickets are drawn at random from the box without replacement until a number appears that has appeared before.
