I have two questions. I tried many times. I don't know where I'm going wrong.

1. ) A study reports that LD % of Americans support increased funding for public schools. If 6 Americans are chosen at random , what is the probability that a. ) All 5 support b. ) None of the s support ( .) At least one of the s support 2. Pollsters are concerned about declining Levels of cooperation among persons contacted. In surveys, A pollster contacts 73 people in the 18-2 1 age bracket and finds that 62 of them respond and I/ refuse to respond when 286 people in the 22- 29 age bracket are contacted, 209 respond and 2 7 refuse to respond. Assume that I of the 369 people is randomly selected . Find the probability of getting someone in the 18- 21 age bracket OR someone who retires to respond . ( Rounded to one decimal place occuracy)
