A die is loaded, and it has been determined that the probability distribution associated with the experiment of rolling the die and observing which number falls uppermost is given by the following: Simple Event Probability {1} 0.18 {2} 0.2 {3} 0.2 {4} 0.19 {5} 0.11 {6} 0.12 (a) What is the probability of the number being even? (b) What is the probability of the number being either a 1 or a 6? (c) What is the probability of the number being less than 4?
