Question

Cards numbered from 11 to 60 are kept in a box. If a card is drawn at random from the box, find the probability that the number on the drawn cards is
(i) an odd number
(ii) a perfect square number
(iii) divisible by 5
(iv) a prime number less than 20

Answer 1

Answer:

this is the answer of this question

Answer 2

(i) Probability of an odd number = 1/2

(ii) Probability of a perfect square number = 2/25

(iii) Probability of a number divisible by 5 = 1/5

(iv) Probability of a prime number less than 20 = 2/25

Step-by-step explanation:

Cards numbered from 11 to 60 are kept in a box.

Total number of outcomes = 50

Number of odd numbers between 11 to 60 = 25

Number of perfect squares between 11 to 60 = 4

Number of multiples of 5 between 11 to 60 = 10

Number of prime numbers less than 20 between 11 to 60 = 4

(i) Probability of an odd number = 25/50 = 1/2

(ii) Probability of a perfect square number = 4/50 = 2/25

(iii) Probability of a number divisible by 5 = 10/50 = 1/5

(iv) Probability of a prime number less than 20 = 4/50 = 2/25
