Question

A bag contains 2 red, 8 blue, and 8 green marbles. Grant picks one at random and keeps it. Then Bailey picks a marble. What is the probability that they both select a red marble? ​

Answer 1

the number of red marbles ÷

the number of marbles

`(2)/(18) = (1)/(9)`

Therefore the probability that they both select a red marble is 1/9
