Abox contains 8 dimes, 15 quarters, and 27 nickels. a student randomly draws two items, one at a time without replacement, from the bag. find the probability that 2 quarters are drawn.

First, we have to find the ratio of quarters to the ratio of total coins:

15/15+8+27 = 15/50

Then, multiply the ratios:

15/50 * 14/49

(14/49 since one quarter has already been removed)

210/2450

21/245 = 0.0857

The probability is about 9 percent.

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
