SOLUTION: There are two spinners. The first spinner is a circle that is cut in fours. the numbers read 10, 12, 14, 18. The other spinner is also cut in fours and the numbers are 1, 2, 3, 4

Question 140064: There are two spinners. The first spinner is a circle that is cut in fours. the numbers read 10, 12, 14, 18. The other spinner is also cut in fours and the numbers are 1, 2, 3, 4
Ok.. The two spinners shown are spun and the difference between the results is found. Find the probability that the difference is a multiple of 3.

The total different outcomes of the two spinners are
4* 4= 16
The outcomes are (10,1),(10,2),(10,3),(10,4),(12,1),(12,2),(12,3),(12,4),(14,1),
(14,2),(14,2),(14,3),(18,1),(18,2),(18,3),(18,4)

Out of these pairs, the ones for which the difference is multiple of 3 are:
(10,1), difference 9
(10,4) difference 6
(12,3) difference 9
(14,2) difference 12
(18,3) difference 15
So the required probability = favorable outcomes/ total outcome
= 5/16
