A random experiment consists of drawing a ball from an urn that contains 4 red balls (numbered 1, 2, 3, 4) and three black balls numbered (1, 2, 3). Precisely state what outcomes are contained in the following events: 1. E1 = The number on the ball is even. 2. E2 = The color of the ball is red and its number is greater than 1. 3. E3 =. The number on the ball is less than 3. 4. E4 = E1 U E3. 5. E5 = E1 U (E2 E3). If all balls in the preceding problem are equally likely to be drawn, nd the probabilities of E;, l 5 i 5 5
