Example Problem 1

A conservative design team, call it C, and an innovative design team, call it N, are asked to separately design a new product within a month. From past experience we know that:
(a) The probability that team C is successful is 2/3.
(b) The probability that team N is successful is 1/2.
(c) The probability that at least one team is successful is 3/4.
If both teams are successful, the design of team N is adopted. Assuming that exactly one successful design is produced, what is the probability that it was designed by team N?
