Answer:

So, the probability is P=0.041.

Step-by-step explanation:

We know that  45% of people in Fast-Food restaurants order a diet drink with their lunch.

We conclude that the probaility p=0.45 that a person order a diet drink.

We calculate the probability that the fourth person orders a diet drink.  

We get:

[tex]P=p^4\\\\P=0.45^4\\\\P=0.041\\[/tex]

So, the probability is P=0.041.
