Andy spins a fair spinner numbered 1 - 5 and rolls a fair dice.
What is the probability of obtaining a multiple of 4 and a factor of 15?
+128406 Here are the possible outcomes :
1,1 1,2 1,3 1,4 1,5 1,6
2,1 2,2 2,3 2,4 2,5 2,6
3,1 3,2 3,3 3,4 3,5 3,6
4,1 4,2 4,3 4,4 4,5 4,6
5,1 5,2 5,3 5,4 5,5 5,6
We have 30 possible outcomes
Those which are multiples of 4 and factors of 15 (in any order) are in red = 6 outcomes
So....the probability is 6 / 30 = 1 / 5
