Chemistry books, on the other hand, are twice as likely as biology, and biology and physics are equally likely to be chosen. [10 Marks] i. What is the probability of being taken out for each subject? [4M] ii. Calculate the probabilities that Mathematics or Biology is taken out by the student. [3M] 2. If A and B are events of mutually exclusive and P(A) = 0.4 and P(B) = 0.5, find: [5 Marks] i. P(A UB) ii. P (AC) iii. P(AC n B)
