Question

In your short presentation, you will be describing an example that uses discrete probabilities or distributions. Provide an example that follows either the binomial probabilities or any discrete probability distribution, and explain why that example follows that distribution.

*Can we please not use a coin example if possible

Answer 1

Firstly , let us discuss about discrete probability distributions :

The probability distribution which describes the probability of occurrence of each value of a discrete random variable.

Where, discrete random variable is a random variable that has countable values . Such as a list of natural numbers.

For example, An ice- cream seller records the total amount of Vanilla , Chocolate and Strawberry flavors, he sold each day for two weeks :

	Vanilla	Chocolate	Strawberry
Day 1	130	70	50
Day 2	120	50	50
Day 3	180	90	80
Day 4	190	100	40
Day 5	150	70	50
Day 6	160	50	60
Day 7	140	40	30
Day 8	170	80	30
Day 9	160	70	60
Day 10	180	100	70
Day 11	160	50	30
Day 12	190	50	40
Day 13	130	70	70
Day 14	140	40	50

Here, we can see that each value is a whole number and certain countable (i.e. discrete random variable) .

and Now, we are looking for it's Discrete Probability Distribution :

Number	Frequency	Probability
120	1	0.071
130	1	0.071
140	2	0.143
150	2	0.143
160	3	0.214
170	1	0.071
180	2	0.143
190	2	0.143

Here, we can see that each value if "Number" is an example of Discrete Random Variable and

Total sum of probability is exactly equals to 1 .So, this represents Discrete Probability Distribution.

Hence , the above example follows discrete distribution.

We can take any example having discrete random variables.
