Question Al At the college enquiry counter, each enquiry received is handled by Adam, Billy or Cathy. The probabilities of them handling with an enquiry are 0.2, 0.3 and 0.5 respectively. • Of enquires handled by Adam, 60% are answered immediately, 25% are answered later the same day and the remainder are answered at a later date. • Of enquires handled by Billy, 75% are answered immediately, 15% are answered later the same day and the remainder are answered at a later date. • Of enquires handled by Cathy, 90% are answered immediately and the remainder are answered at a later date. Find the probability that an enquiry (a) is handled by Cathy and answered immediately; (b) is answered immediately; (c) is handled by Adam, given that it is answered later the same day.
