What is Probability ?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.
The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Probability Formula = f/n
where,
f is the number of times an event occurs
n is the total number of trials
The probability is represented as:
P(Large | Hot)
This is calculated using:
P(Large | Hot) = n(Large and hot)/n(hot)
Using the data on the given table, we have:
P(Large | Hot) Â = 22/(8 + 12 + 5)
P(Large | Hot) Â = 0.88
In percentage
P(Large | Hot) Â = 88%
Hence, the probability that a customer ordered a large given that he or she ordered a hot drink is 88 % .
