Gino is buying wood screws at the corner hardware store. the table shows different numbers of bags of screws and their corresponding prices.

according to the table, the relationship between the number of bags and the price is:
a) proportional
b) not proportional

It would be proportional because 
10 / 2 = 5
20 / 4 = 5
35 / 7 = 5 

There are total 10 juice boxes
P(grape) first pick:
2/10=1/5
P(grape) second pick:
1/9
As a result, the probability that, when Jill reaches into the cooler to grab two juice boxes without replacing them, she grabs two that are grape is 1/45. Hope it help!
