Answer:
a) Discrete, because the number of point scored during basket ball is countable.
For instance, the amount of point scored in a basketball could be 75, 103, 63 etc. The numbers are countable
b) Continuous, because the amounts of rainfall is a random variable that is uncountable.
For instance, the amount of rainfall in City Upper B during April could be 0.10 inches of rain per hour, 0.30 inches of rain per hour. This numbers are not countable, they are rather approximated or rounded off.
Step-by-step explanation:
A random variable is considered discrete if its possible values are countable while a random variable is considered to be continuous if it's possible values are not countable.

Answer:
The smaller pipe can fill the tank in 6 hours alone.
Step-by-step explanation:
Let us assume that the smaller pipe can fill the tank alone in x hours and the larger pipe fills it in (x - 3) hours.
Therefore, the smaller pipe in 1 hour can fill part of the tank.
Again the larger pipe in 1 hour can fill part of the tank.
So, if both the pipes are open then, in 1 hour they can fill ( part of the tank.
Therefore, they can fill the full tank in hours.
As per given condition, we can write
⇒ x² - 3x = 4x - 6
⇒ x² - 7x + 6 = 0
⇒ (x - 6)(x - 1) = 0
⇒x = 6 or x = 1
But x can not be less than 2 hours.
So, x = 6 hours.
Therefore, the smaller pipe can fill the tank in 6 hours alone. (Answer)
