I need help to answer this.(adsbygoogle = window.adsbygoogle || []).push({});

In a game of two up, twqo coins are tossed, bets are placed on whether coins give even (HH or TT) or odss (HT or TH). In the previous 8 games, evens has occured each time. What is the best bet on the ninth game?

This is what i did but i dont think tis right

P = 1/(2^8) (Probability of 8 evens) + 0.5 (Probability of 1 odd)

Also i have one other q.\\A blind person has 3 drawers of sock. Each draw contains a red, black and white sock. If a sock is taken from each draw:

what is the probability of two socks are black?

what is the probability that one sock is red?

For these 2, i calculated the number of ways= 3^3 = 27, but dont know how to go from here

Thanks
