Question

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

Answer 1

tossing a coin n times or tossing n coins simultaneously are same things.
AND the no. of outcomes are 2^n.

Here the answer is 2³ = 8

Answer 2

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:

$2^n$

where:

• n is times or tossing n coins simultaneously are same things.

Knowing the value of n we find that:

$n=3\\2^n=2^3=8$
