Explanation:
If we denote the events as:
Then the evemt we are looking for can be described as the alternative A or B (
The probability can be calculated using the formula:
Now we have to calculate the probabilities on the right side:
Finally if we substitute calculated values we get:
This result can be simplified because both numerator and denominator can be divided by
So the answer can be written as:
The probability is
