b. Construct a discrete probability distribution using X as the number of
heads of the two-coin toss.

(some of your vocabulary an notation is unfamiliar to me....)

a. The sample space is {HH, HT, TH, TT}

b.
P(HH) = (1/5)(1/5) = 1/25
P(HT) = (1/5)(4/5) = 4/25
P(TH) = (4/5)(1/5) = 4/25
P(TT) = (4/5)(4/5) = 16/25

P(X=2) = 1/25
P(X=1) = 8/25
P(X=0) = 16/25

c.
