A coin is biased so that a head is twice likely as a tail.
P(head) = 0.666 ; p(tail) = 0.333
---------------------------------------------
If the coin is tossed three times
Find the probability distribution for the number of heads
P(x = 0) = 0.333^3 = 0.037
P(x = 1) = 3*0.666*0.333^2 = 0.2216
P(x = 2) = 3*0.666^2*0.333 = 0.4431
P(x = 3) = 0.666^3 = 0.2954
---------------------------------------------
