Khalid has a game board as shown below, which is a square with 20-cm sides. The area of the largest circle is 320 square centimeters.

What is the probability of scoring 1, 3, or 5 points with one randomly thrown dart?

A. 1/2
B. 5/8
C. 3/4
D. 4/5

Answer 1

D. 4/5

Explanation:

Answer 2

Option D. 4/5

Explanation:

we know that

The probability of scoring 1, 3, or 5 points with one randomly thrown dart is equal to divide the area of the largest circle by the area of the square game board

step 1

Find the area of the square game board

`A=b^(2)`

we have

`b=20\ cm`

substitute

`A=20^(2)`

`A=400\ cm^(2)`

step 2

Find the probability

`P=320/400`

`P=0.8=8/10=4/5`
