Obtuse angles are greater than 90 degrees, or are wider than a right angle. These are all acute angles in this diagram because they are all less than 90 degrees.
There are 37 jelly beans so p for the first one is 27/37. That leaves 36 in the bag. So p for the second jelly bean is 10/36=5/18. The combine probability is 27/37×5/18=3/37×5/2=15/74.
