Question

A bag contains 4 white tiles and 8 black tiles. You select one tile at random from the bag. What is the probability that you select a black tile?

Answer 1

Answer:

p( black) = 2/3

Step-by-step explanation:

4 white + 8 black = 12 tiles

P ( black) = number of black / total

                = 8 /12

                 = 2/3
