When a biased coin is tossed, heads is three times as likely to come up as tails. Rearrange the following procedure in the correct order to find the probability that should be assigned to the outcome of heads and tails? 1. p(T) = 1/4 and p(H) = 3/4
2. since heads and tails are the only two outcomes p(H) + p(T) = 1.
3. p(H) = 3p(T)
4. 3p(T) + p(T) = 1
5. 4p(T) = 1
