Answer:

The path length is the same for the small and large semicircles.

Step-by-step explanation:

The distance around the large semicircle = 1/2 * π * diameter

= 1/2*8*π

= 4π m.

The distance around the 2 smaller semicircles

= 1/2 * 4 * π + 1/2 * 4 * π

= 2π + 2π

= 4π m.

Whether the events are dependent or not, the rule for conditional probability applies:

0.25×0.4 = P(a∩b) = 0.1

The appropriate choice is
