“Cards marked with numbers 13, 14, 15,……,60 are placed in a box

1.	“Cards marked with numbers 13, 14, 15,……,60 are placed in a box and mixed thoroughly. One card is drawn at random from the box.” Read the information carefully and match the following.1) p → iv , q → iii , r ii , s→ i 2) p → iii , q → ii r → iv , s → i 3) p → i , q → ii, r → iii s → iv 4) p→ ii, q → iv, r → i , s → iii
Answer» 4) p→ ii, q → iv, r → i , s → iii (i) Numbers divisible by 5 : 15, 20, ….., 60 = 10 numbers Total numbers = 60 – 12 = 48 Probability = 10/48 = 5/24 (ii) Primes: 13, 17, 19, 23, 29, 31, 37, 41, 47, 53, 59 Total = 12 P = 12/48 = 1/4 (iii) Multiples of 19 = 19, 38, 57 P = 1 – Probability of prime = 1 - 1/4 = 3/4 = 36/48

Answer»

4) p→ ii, q → iv, r → i , s → iii

(i) Numbers divisible by 5 : 15, 20, ….., 60 = 10 numbers

Total numbers = 60 – 12 = 48

Probability = 10/48 = 5/24

(ii) Primes: 13, 17, 19, 23, 29, 31, 37, 41, 47, 53, 59

Total = 12

P = 12/48 = 1/4

(iii) Multiples of 19 = 19, 38, 57

P = 1 – Probability of prime = 1 - 1/4 = 3/4 = 36/48
