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

Step-by-step explanation:
The question is mixed up. The only clear question is:
Given:
4, 7, 10, 13, 16, 19
Required
Write the next 4
Notice that the rule of the above sequence is to "add 3". So, the next 4 numbers is gotten by adding 3 to the previous number on the sequence.
The next 4 are:
