gold and silver have densities of 19.3 and 10.5 grams per cubic centimer, respectively. If you have eual volumes of each, which one will have the larger mass? I am thinking the gold. how do i prove it? Thank you

Any 2 of 12 is (12 x 11)/2 = 66. Any 2 from 6 is (6 x 5)/2 = 15 so the probability is 15 out of 66 ie 0.227 or 22.7% Loui

You can apply enough force to the head of a pushpin to push it into a plaster wall with your thumb. However, it is not a good idea to try to do this with a needle. Use the concept of pressure to explain the differnce betweeen these two situations. Thank you
