Four fair coins are flipped. Each coin tail is recorded as a 0 and a head as a 1 and the source symbol is the sum, with X1 corresponding to sum =0, X2 to sum = 1, etc. The probability of the source producing X3 equals _______.

Fill in the blank(s) with the appropriate word(s).


here are 16 possible outcomes (0000 to 1111) and each outcome has the same probability. X3 occurs when sum =2, or the 6 outcomes (0011, 0101, 0110, 1001, 1010, 1100) making its probability 6/16 = 3/8
