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 :

$\text{Probability =}\frac{5}{12}$

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

$\text{Probability}=\frac{5}{12}\cdot\frac{5}{12}=\frac{25}{144}$

The answer is a :

$\frac{25}{144}$
