The density function is just the piecewise function,
i.e. a rectangle of height
and length 17 plotted over the interval ![[5,22]](https://tex.z-dn.net/?f=%5B5%2C22%5D)
. Any probabilities that you need to find are then areas of smaller rectangles.

Answer:
After 20 months
Step-by-step explanation:
This is a compound growth problem which has the formula:
Where
F is future value
P is present amount
r is the rate of growth
t is the time (in months)
Future amount is $65, what he needs at-least
P is the initial amount, that is $10
r is the rate of growth, which is 10% or 10/100 = 0.1
t is time in months, what we need to find
Substituting and solving we get:
<u>He would need 19.64 months to save up at-least 65. So, that means, he would need 20 months</u>
