8) 6!/(3!*2!) = 60
option C) is correct
9) 7 = 1+6 = 2+5 = 3 +4 = 4+3 = 5+2 = 6+1
hence required probability =6/36
option C) is correct
10) 12 = 6+6
hence required probability =1/36
option a) is correct
11)there are 6 number
hence required probability =6/36
option C) is correct
12) P(|X -Y| = 1)
(1,2),(2,3),(3,4),(4,5),(5,6),
similarly its opposite
hence required probability =10/36
option A) is correct
13)
P(|X-Y| = 5)
(1,6),(6,1)
hence required probability =2/36
option B) is correct
14)
True , this is pascal' rule
15)P(X=3) = 6C3 * 4C2 / 10C5 = 20 * 6 / 252 =20/42
option B) is correct
16)
P(X=5) = 6C5 * 4C0 / 10C5 = 6/ 252 = 1/42
option A) is correct
17) required probability = 6C2 * 3C1 = 15*3 = 45
option C) is correct
18) mean = 3
option C) is correct
19) variance = 2.5
20)median = 3
