0.28

Answer 8

Cuz the chance of him being the president is seventy pervent right, imagine he did i become a president by that 70 percent and there is also a 40 chance to consider . so you have to multiply them together and we can call them fundamental counting principle.

Answer 9

Ok the answer is 0.28 because you need to multiply the two together. but first you need to put them to decimals so 40% turns into 0.40 and 70% turns into .70 and when you multiply them you get 0.28 or 28%
