There are five coins that look identical in a box. however, these coins are not fair. the probability of getting heads is 0.1 for coin i, 0.3 for coin ii, 0.5 for coin iii, 0.7 for coin iv, and 0.9 for coin v. a coin was picked randomly from the box and was tossed. a head was observed. i) what is the probability that the vth coin was chosen. ii) the coin was tossed again (you still do not know the identity of the coin but you know you had a head in the first toss). what is the probability that you will get another head? iii) suppose both the tosses resulted in heads. what is the probability that the 3rd toss of the same coin will result in a tail?
