Hey!
Grape over total: 
After he drinks 1, there will be 1 less. That means it will be over 11
Orange over total: 
Now multiply the fractions

That means the probability is: 
Good luck and hope this helps! :)
It is easier to do if we get rid of the decimals, so lets multiply both numbers by 10:
5.8/1.2 = 58/12
and reduce the fraction:
= 29/6

= 4.83
59.96.
If you distribute 4 to 14.99 then you get the answer above.
