5. Scientists test two types of seed, A and B, in a country where the probability of good rainfall in any given year is 0.4. Type A seed is found to have probability of growing of 0.9 when the rainfall is good, but only of 0.3 when it is poor. a. i) Complete the tree diagram below for Type A seed 0.9 Seed grows Good rainfall 0.4 Seed does not grow Seed grows Poor rainfall Seed does not grow i. Calculate the probability that there is good rainfall and the seed of type A grows. i) Calculate the probability that type A seed grows whatever the rainfall
