Statement 1: Probability of prime numbers less than 20 is \[\frac{2}{25}.\] |
Statement 2: Probability of perfect square is \[\frac{9}{100}.\] |
A) Only Statement-1
B) Only Statement-2
C) Both Statement-1 and Statement-2
D) Neither Statement-1 nor Statement-2
Correct Answer: C
Solution :
Statement -1: Total number of outcomes = 100 Number of favourable outcomes of getting a number which is a prime less than 20 is {2, 3, 5, 7, 11, 13, 17, 19} i.e. 8. Required probability Statement-2: Number of favourable outcomes of getting a number which is a perfect square is {4, 9, 16, 25, 36, 49, 64, 81, 1000} i.e. 9 Required probabilityYou need to login to perform this action.
