Question

two different coins are tossed together find the probability of (i) getting a doublet (ii) of getting a sum 10,of the numbers on two dice

Answer 1

(i) total outcomes = 36
Favourable outcomes = (1,1) (2,2) (3,3) (4,4) (5,5) (6,6)
=6

P(E) = 6/36
= 1/6

(ii) total outcomes= 36
Favourable outcomes = (4,6) (5,5) (6,4)
= 3

P(E) = 3/36
= 1/12
