Question

Cards marked with number 3, 4, 5, …, 100 are placed in a box and mixed thoroughly. A card is drawn at random from the box. Find the probability that the number on the selected card is:
i) divisible by 9 and is a perfect square.
ii) a prime number less than 17.

Answer 1

Step-by-step explanation:

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

i) E = divisible by 9 and is a perfect square

so P(E) = 2/100 = 1/50

ii) E = prime no. less than 17

so P(E) = 6/100 = 3/50
