Question

Two six-part spinners are numbered 1 to 6. What is the probability that both numbers will match if the spinners are spun once each?

Answer 1

It’s one sixteenth 1/16

Answer 2

There are 36 possible outcomes

11 12 13 14 15 16

21 22 23 24 25 26

31 32 33 34 35 36

41 42 43 44 45 46

51 52 53 54 55 56

61 62 63 64 65 66

There are 6 matching outcomes

11 12 13 14 15 16

21 22 23 24 25 26

31 32 33 34 35 36

41 42 43 44 45 46

51 52 53 54 55 56

61 62 63 64 65 66

P(matching) = number of matching / total

= 6/36

= 1/6
