Chapter 10, Problem 12CT

To determine

Tocalculate:

The probability of meteorite that will hit land or water.

Answer to Problem 12CT

The probability of the meteorite that will hit on the land is $0.29$ .

Explanation of Solution

Given information:

Surface area of earth $=196.9$ million square miles.

Land area $=57.5$ million square miles.

Calculation:

It is given that surface area of earth is $196.9$ million square miles, land is $57.5$ million square miles and $139.4$ million square miles. It is said that the meteorite will hit the land of the earth.

The probability that meteorite hits land is as follows:

  $\begin{array}{l}P\left(meteoritehitsland\right)=\frac{areaofland}{areaoftotalsurface}\\ =\frac{57.5}{196.9}\\ =0.29\end{array}$

Therefore, the probability of the meteorite that will hit on the land is $0.29$ .
