31% of adults would pay more for environmentally friendly products. you randomly select 10 adults. find the probability that the number of adults who would pay more for environmentally friendly products is (a) exactly two, (b) more than two, and (c) between two and five, inclusive.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
