Question

Two identical spinners each have five equal sectors that are numbered 1 to 5. what is the probability of a total less than 9 when you spin both these spinners ? A 3/25 B 6/25 c4/5 D 22/25​

Answer 1

A) 3/25

Explanation:

2 spinners with 5 sectors numbered 1 to 5 gives 25 possible outputs.

Spinner 1 + Spinner 2

1 + 1

1 + 2

1 + 3

1 + 4

so on...

If you use the same pattern to find all 25 outputs, then the results show 3 possibilities of a total less than 9 when you spin both these spinners.

• 4 + 5 = 9
• 5 + 4 = 9
• 5 + 5 = 10
