There are two names given JOHNSON and JONES. If one letter is picked from both simultaneously at random, then find the probability that the letter is same?
Choose the correct choice from the following options:	A) 24/35	B) 17/35	C) 8/25	D) 6/35	E) 1/25
This question can also be solved by using 'brute force' - you just have to 'map out' the possibilities.   The nameJohnsonhas 7 letters and the nameJoneshas 5 letters, so there are (7)(5) = 35 possible pairings of letters that can occur.   Of those 35, the pairings that include the SAME letter both times are:   J and J   1st O and O   1st N and N   S and S   2nd O and O   2nd N and N   Total: 6   So the probability that the two randomly selected letters will match is 6/35.   6/35
