Probabilities are used to determine the chances of events.

The probability P(the stock performs below average|domestic) is 0.109

How to calculate the probability

Let A represent the number of stocks that performs below average

B represents the number of domestic stock

From the table, we have:

n(A n B) = 55 i.e. domestic stocks that performs below average

n(B) = 505 i.e. all domestic stocks

The probability is then calculated as:

[tex]P(A\ |\ B) = \frac{n(A\ n\ B)}{n(B)}[/tex]

This gives

[tex]P(A\ |\ B) = \frac{55}{505}[/tex]

[tex]P(A\ |\ B) = 0.109[/tex]

Hence, the probability P(the stock performs below average|domestic) is 0.109
