I need help asap. If you could answer both, I'd be grateful. I'll give a thumbs up, thanks. Only a brief explanation is needed.

For any two disjoint events E and F, P(EVF) = P(E) + P(F) Select one: O True O FalseMuscular dystrophy is a genetic disease caused by a mutation on the X chromosome. During reproduction this mutation arises spontaneously on each of the X chromosomes of the parents, independently and with probability ,u = 0.884. We can therefore view the production of a child as consisting of two probabilistic experiments. Firstr one of the two sex chromosomes is chosen with equal probability from each parent. Second, for each X chromosome that is chosen, the muscular dystrophy mutation arises independently with probability ti. All male children carrying the mutation will develop muscular dystrophy, whereas only females whose X chromosomes both carry the mutation will develop the disease. What is the probability that a child will develop the disease? Round your answer to five decimal places
