Ashelf has 20 bags of potatoes. two of the bags have potatoes starting to go bad. what is the expected probability of the complement of the event "bad bags of potatoes"?

a.) 0.1

b.) 0.2

c.) 0.8

d.) 0.9

 There are 2 bad bags out of 20, so the probability of bad bags is: 
 

But we want the complement, which is the probability of bags which are not bad, and that is :

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

b) well because you get well
