1 answer:
Savatey [412]3 years ago

Answer:

  • <u>0.45</u>

Explanation:

<em>The probability that the rainfall for the year is less than 8 inches</em> is equal to the area under the curve of <em>the probability density function</em> to the left of 8 inches.

I attached a graph with the squares that cover that area in red.

There are 7 complete, or almost complete, red squares and 4 triangles.

For estimation purposes, you can count each triangle as half a square.

Thus, consider 7 + 4/2 = 7 + 2 = 9 squares.

Since <em>the area of each square on the grid is 0.05</em>, the area o 9 squares is:

  • 9 × 0.05 = 0.45

Hence, your <em>estimate of the probability that the rainfall for this year is less than 8 inches is 0.45.</em>
