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.
Step 1) Add x to both sides and simplify
1+4x=4
Step 2) Subtract 1 from both sides
4x=3
Step 3) Divide everything by 4
x=4/3 (1 1/3) (1.333)
62.5%
to change a fraction to a percent multiply by 100%
0.625 × 100% =62.5%
