Consider the type of clothes dryer (gas or electric) purchased by each of five customers at a certain store. a. if the probability that at most one of these purchases an electric dryer is 0.428 what is the probability that at least two purchase an electric dryer?

Let event E = the event that at most one customer purchases an electric dryer (1 or 0 customer). Then E' is the event that at least two purchase electric dryers (2 or 3 or 4 or all 5 purchase an electric dryer)P(E′) = 1 – P(E) = 1 - .428 = .572

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
