Consider the type of clothes dryer (gas or electric) purchased by each of five different customers at a certain store. (a) If the probability that at most one of these purchases an electric dryer is 0.422, what is the probability that at least two purchase an electric dryer?

0.578

Step-by-step explanation:

Given that

The probability that at most one of these purchases an electric dryer  = 0.422

Since the most one of these purchase probability is given i.e 0.422

So, the  probability of at least two purchase an electric dryer is

= 1 - most one of these purchase probability

= 1 - 0.422

= 0.578

Basically, we subtracted the given probability with the one

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

answer: for each 3 girls there is 2 boys . 3: 2
