Caroline flips a coin 3 times. According to the tree diagram, how many possible outcomes exist?
A) 2
B) 4
C) 6
D) 8

In this exercise we want to use probability to calculate the chance of an event occurring, so we find that:
Letter D
Knowing that the probability formula is given by:
[tex]2^n[/tex]
where:
Knowing the value of n we find that:
[tex]n=3\\2^n=2^3=8[/tex]
