Suppose you drop a tie at random on the rectangular region shown in Fi

1.	Suppose you drop a tie at random on the rectangular region shown in Fig. below. What is the probability that it will land inside the circle with diameter 1 m?
Answer» Area of circle with radius 0.5 m A circle = (0.5)2 = 0.25πm² Area of rectangle = 3 ×2=6m² Probability (geometric) = (measure of specified region part)/(measure of whole region) Probability that tie will land inside the circle with diameter 1m = (area of circle)/(area of rectangle) = 0.25πm²/6m² = (1/4)x(π/6) = π/24

Suppose you drop a tie at random on the rectangular region shown in Fig. below. What is the probability that it will land inside the circle with diameter 1 m?

Answer»

Area of circle with radius 0.5 m

A circle = (0.5)2 = 0.25πm²

Area of rectangle = 3 ×2=6m²

Probability (geometric) = (measure of specified region part)/(measure of whole region)

Probability that tie will land inside the circle with diameter 1m

= (area of circle)/(area of rectangle)

= 0.25πm²/6m²

= (1/4)x(π/6)

= π/24
