Directions: Select three of the spinners from the image below (you may pick more than one of each) such that the total number of sectors in all three spinners totals 10. Select spinners so that the probability of all three spinners landing in the shaded sector is the smallest (or largest).

Extension: How would the answer change if you could create any number of spinners instead of exactly 3 spinners such that the total number of sectors totals 10? (e.g. 1 spinner with 10 equal sectors or 5 spinners each with 2 equal sectors)

### Hint

### Hint

How can you make the probability the smallest (or largest) number possible?

### Answer

### Answer

2) 1/2 * 1/3 * 1/5 = 1/30

3) 1/4 * 1/4 * 1/2 = 1/32

4) The least probability: 1/3 * 1/3 * 1/4 = 1/36

1: the greatest probability is 1/2 * 1/2* 1/6= 1/24

2: 1/2* 1/3* 1/5= 1/30

3:1/4* 1/4* 1/2= 1/32

4: the least probability is 1/3* 1/3* 1/4= 1/36

the last one has the least probability of shaded.
