Step-by-step explanation:
we know that
The probability of an event is the ratio of the size of the event space to the size of the sample space.
The size of the sample space is the total number of possible outcomes
The event space is the number of outcomes in the event you are interested in.
so
Let
x------> size of the event space
y-----> size of the sample space
so
step 1
Find the probability that a randomly selected person was female
In this problem we have
----> total females
---> total males plus total females
substitute
step 2
Find the probability that a randomly selected person was was wearing brown shoes
In this problem we have
----> total brown shoes
---> total shoes
substitute
step 3
Find the probability that a randomly selected person was either female or was wearing brown shoes
Adds the probabilities
