Answer: 2
Step-by-step explanation:
obvious
Answer:
science = 
English = 
Math = 4 hours
Step-by-step explanation:
let the number of hours spend on science = x
Hence the number of hours on English will be = 2x
Given that the number of hours spend on science is one third of the time spend on maths. Hence the time spend on math is 3 times that of the time spend on science. That the time spend on maths is = 3x
Hence the total time to study is
x+2x+3x
which is given as 8 hours
Hence
x+2x+3x =8
6x=8
dividing both sides by 6
Hence the number of hours foe studying science = 
Number of hours to study English = 
=
Number of hours to study Math= 
=
Simplify the expression.

This count is a discrete random variable (option A).
<h3>What is a
discrete random variable?</h3>
A discrete random variable is a variable that contains integers that can only be a limited number of possible values. A discrete random variable is can contain only a finite set of numbers .
An example of discrete random variable is the number of students in the first period class. It is impossible for the number of students in the class to go on indefinitely.
Discrete random variable has the following properties:
- It is finite
- It is numeric
- It is countable
- It contains non-negative integers.
A continous random variable is a variable that has an infinite number.
