Explanation / Answer

12)

a) P(X=4) = 1/6

b) P(X= even) = (1+1+1)/6 = 1/2

X can be 2,4,6

c) P(X>4)

X can be 5 or 6

So P(X>4) = 2/6 = 1/3

d) P(X<7) so x can be 1,2,3,4,5,6

P(X<7) = 6/6 = 1

e) P(X>0) = 1

f) P(X>3 or X = odd number)

X can be 1,3,4,5,6

P(X>3 or X = odd number) = 5/6

g)

P(X>3 and X = odd number)

So X can be only 5

P(X>3 and X = odd number) = 1/6
