Math 128 There are three different types of jewelry on a table: earrings, necklaces and rings. For each of these, there are gold, silver and rose gold pieces. The probability of each type of jewelry being on the table is given in following chart: A piece of jewelry is selected at random from this table. (a) Find the probability the piece of jewelry is gold. (b) Find the probability the piece of jewelry is an earring. (c) Find the probability the piece of jewelry is a gold earring or is a silver ring

Part b.

probability of all pieces of jewelry is earring = sum of all earring probability

P = 0.07 + 0.15 + 0.13

= 0.35
