Three identical slips of paper with the numbers 1, 2 and 3 (one number on each slip)are placed in a box. One slip is randomly selected, and then, without replacement, asecond slip is selected. Find the probability that the sum of the two numbers is even.A sample space is composed of three outcomes, called A, B and C. Outcome A istwice as probable as B, and B is twice as probable as C. Find the probabilities of theevents of A, B and C.1.а.b.
