Answer :
The experimental probability of an event is based of an actual experiment. It depends on what has already happened with the experiment.
Probability of an Event P(E) = Number of times an event occurs / Total number of trials
• In this problem, the total number of trials is the total number of customers.
,• The number of times event occured is the number of customers who wanted mustard on their hotdog.
Thus,
Given,
--- 10 customers
--- Out of which 3 wanted mustard
Thus, the probability that the next customer will want mustard is 3 over 10, or
