A box contains four cents, of which two centss have heads on both their faces, one cent has tail on both its faces and the fourth cent is a normal one. A cent 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 cent tossed is also a head.	Pick one:  A) 4/5  B) 3/5  C) 2/5  D) 3/4  E) 1/2
There are four ways (2 heads in one two-headed cent and 2 heads in the other two-headed cent)   How many ways can you get heads from this entire set of cents? There are five ways (four as identified above and one from the normal coin)   Therefore probability = 4/5   Option 4/5
