determine whether the random variable is discrete or continuous

1 The amount of rain in City B during April

A- The random variable is continuous

B- The random variable is discrete

2 The number of statistics students now reading a book

A- The random variable is continuous

B- The random variable is discrete

Solution

1. The amount of rain in city B during April

ans: the variable is continuos random because it has an infinite no. of possible values are not countable. it can be plotted in a line in uninterrupted fashion. they will varry from low to high values.

here rain during the month April may varry from low to high as a continuos variable.

2. The number of statistics students now reading a book

ans: the variable is discrete random variable because it has either a finite no. of possible values or a countable no. of possible values. the vaues can be plotted on a line with space between the points. they can take seperate values.

here no. of students now reading a book can take a countable as a discrete values.
