Formula :
Probability = Favorable outcome/Total outcome
Total outcome of rolling a cube :
1,2,3,4,5,6
Total outcome = 6
Favorable outcome (even number) = 3 (2,4,6)
Probability = 3/6
= 1/2
Favorable outcome (6) = 1
Probability = 1/6
So, Total Probability = 1/2 × 1/6
= 1/12
Probability (in %) = 1/12 × 100%
= 8.33 %
Hence, P(even and then a 6) = 8.33 %
