Each of three persons fires one shot at a target. The outcomes of the shots made by them are recorded. Let A¡ denote the event that the target is hit by person i, i=1, 2, 3. Assume that A1, A2, A3 are mutually independent and that P(A1) = 0.7, P(A2) = 0.9, P(A3) = 0.8. 1. Define the probability space for the outcomes of the shots fired by the 3 2. Compute the probability that exactly two people hit the target (i.e., one misses). persons.
