-48,-49,-50. i got this by dividing -147 by 3 which is -49 and just adding one and subtracting one from it (-48 and -50).
It's the sum of the following probabilities: (4/52) * (36/51) * (35/50) * (34/49) * (33/48) = 1.81% (36/52) * (4/51) * (34/50) * (33/49) * (32/48) = 1.66% (36/52) * (35/51) * (4/50) * (33/49) * (32/48) = 1.71% (36/52) * (35/51) * (34/50) * (4/49) * (32/48) = 1.76% (36/52) * (35/51) * (34/50) * (33/49) * (4/48) = 1.81% total = 8.75%
49
76. 50 plus 27 is 77, and then subtract 1 (50-49) and you get 76.
