Question

A bag contains 5 gray tiles and 2 blue tiles. Jenny reached into the bag and picked a tile randomly, and then without replacing it, picked a second tile. If you know that she picked a blue tile with her first pick, what is the probability that she picked a gray tile with her second pick?

a. 1/6
b. 1/7
c. 5/6
d. 5/7

Answer 1

5/6

Answer 2

You add all the tiles which is 5 gray tiles and 1 blue tile (since she already picked one)

5+1=6

So if she picked one, she would have a
`(5)/(6)` chance of picking a gray tile since there are 5 gray tiles

Answer:
`(5)/(6)`
