In this case, 236 people over 991 said that they checked the portfolio daily, so the empirical probability is
Which you can round as 0.238, i.e. 23.8%.
The simplified expression of is
The expression is given as:
Expressions raise to power 0 is 1.
So, we have:
Apply the law of indices to expression with common base
Evaluate the sum and difference
Remove the bracket
Hence, the simplified expression of is
