3. in his collection, marco has 5 large gold coins, 12 large silver coins, 15 small gold coins, and 3 small silver coins. if he randomly picks a coin, what is the
probability that it is gold, given that it is small?

3/4
5/6
3/7
18/35

5/6

Since it is given that it is small, only worry about the small coins.

There are 18 total small coins and 15 of them are gold so 15/18 is the probability or when simplified = 5/6

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.
