Answer:
Since, total cards = 15
(i) total odd no.'s from 1 to 15 = 8
∴ favorable outcomes= 8
∴ probability = 158
(ii) Total Multiples of 4 from 1 to 15 = 3
∴ favorable outcomes= 3
∴ probability = 153=51
(iii) Total no's divisible by 5 from 1 to 15 = 3
∴ favorable outcomes= 3
∴ probability = 153=51
(iv) Total no's divisible by 2 and 3 from 1 to 15 are:
6,12
∴ favorable outcomes= 2
∴ probability = 152
(v) Total no's less than or equal to 10 from 1 to 15 = 10
∴ favorable outcomes= 10
∴ probability = 1510=32
