Question 1 [2+2+3+2] Two ordinary dice are thrown. Find the probability that the sum of the scores obtained (a) is a multiple of 5, (b) is greater than 9, (c) is a multiple of 5 or is greater than 9, (d) is a multiple of 5 and is greater than 9. Question 2 In a certain selection of flower seeds { have been treated to improve germination and } have been left untreated. The seeds which have been treated have a probability of germination of 0.8, whereas the untreated seeds have a probability of germination of 0.5. (a) Construct a tree diagram to show all probability values. [10] (b) Find the probability that a seed, selected at random, will germinate. [2] (c) The seeds were sown and given time to germinate. Find the probability that a seed selected at random had been treated, given that it had germinated. [2]
