Suppose that all of the points on the circular dartboard shown are equally likely to be hit by a dart. if the radius of the shaded center circle is 1 and the radius of the entire dartboard is 4, what is the probability of throwing a dart and hitting the white part of the board? round your answer to the nearest whole number.

The probability of throwing a dart and hitting the white part of the board is 1.

Step-by-step explanation:

Since we have given that

Radius of shaded center circle = 1

So, Area of shaded center circle is given by

Radius of entire dartboard = 4

Area of entire dartboard is given by

Area of white part is given by

So, Probability of throwing a dart and hitting the white part of the board is given by

Hence, the probability of throwing a dart and hitting the white part of the board is 1.

a. the residual plot for model 1 has a random pattern and is a good fit for the data.
