Indirect Proofs

Hypothesis - I think the dice has 2 dots and by indirect proof I think we will be able to prove it.

Data:




Indirect Proof Work:

a) Total number of faces seen: 1 face x 180
Trials = 180
b) Total number of dots seen: 145
c) Average number of dots per cube: 145/180 = 0.81
d) Average number of dots per cube: 0.81 X 6 = 4.9 (5)


Actual number of dots = 5
