Answer 1

Answer 2

Hey!

Grape over total:
`(4)/(12)`

After he drinks 1, there will be 1 less. That means it will be over 11

Orange over total:
`(5)/(11)`

Now multiply the fractions

`(4)/(12) * (5)/(11) = (20)/(132) \rightarrow (10)/(66) \rightarrow (5)/(33)`

That means the probability is:
`(5)/(33)`

Good luck and hope this helps! :)
