A box contains four dimes, of which two dimes have heads on both their faces, one dime has tail on both its faces and the fourth dime is a normal one. A dime is picked at random and then tossed. If head is the outcome of the toss, then find the probability that the other face (hidden face) of the dime tossed is also a head.	Options:
A) 3/5	B) 4/5	C) 2/5	D) 3/4	E) 1/2
There are four ways (2 heads in one two-headed dime and 2 heads in the other two-headed dime)   How many ways can you get heads from this entire set of dimes? There are five ways (four as identified above and one from the normal coin)   Therefore probability = 4/5   Option 4/5
