If you roll three fair coins what is the probability that youll get at least 2 heads

1/2 or 50%

Step-by-step explanation:

You can use some casework to find your answer.

The first case - only two of the coins are heads.

The possible ways that this could be are:

THH

HTH

HHT

The second case - all three coins are heads.

In this instance, there is only one way that this could happen:

HHH

This is a total of 4 desired outcomes out of 2*2*2=8 possible outcomes, which is a probability of 4/8=1/2. Hope this helps!
