The odds for are: 2/3

Reiny
"probability of odds" ? , no such thing
odds and probability are closely related
odds in favour of some event
= prob(event will happen) : prob(event will not happen)
so two heads in 3 flips could be
HHT
HTH
THH, which would be 3 cases out of the 8
prob of exactly two heads out of 3 = 3/5
prob of NOT exactly two heads out of 3 = 5/8
odds against exactly 2 heads out of 3 flips = 5:3

Suppose a coin is biased so that it has the probilities below for landing on heads or tails on a single toss of the coin.
P(h)=0.5020 P(t)=0.4980
If this coin is tossed twice find the probability P(hh)
