Answer:
It is 14.45 percent
.
Step-by-step explanation:
Explanation:
The first day is independent from the day before. Therefore the first day probability (of rain) is 20 percent.
The second day (depends on the previous day) rainfall probability is 85 percent.
Finally, the third day (it must be rainy to satisfy the total probability) rainfall probability is 85 percent.
The probability of having three consecutive days which are rainy:
P(all rainy)

now, bear in mind that all these ones are lines, and to graph a line all you need is two points, so let's pick a couple of random values for say "x" and let's see what we get for "y" and that's our x,y point.
