Question

coeper below has a congruent sectionsSarah will spin the arrow on the spinner twice. What is the probability that the arrow will landon a shaded section of the spinner on both spinsA1.5 Shorded7 non-SharedсD2549

Answer 1

The probability can be expressed as :

`Probability=\frac{\text{ Shaded Sections}}{\text{ Total Sections}}`

The number of shaded sections is 5.

The number of total sections is 12.

In one spin, the probability is :

`\text{Probability =}(5)/(12)`

Every spin has the same probability of landing on shaded area. Since Sarah spins the spinner twice. The probability now will be :

`\text{Probability}=(5)/(12)\cdot(5)/(12)=(25)/(144)`

The answer is a :

`(25)/(144)`
