Answer:
11/16
Step-by-step explanation:
First, count all outcomes to be placed as the denominator.
There are 16 outcomes.
?/16
Now, observe all 16 outcomes and count the ones with at least 2 heads in the outcome.
For example, HHHH and HHHT are included because they have 4 and 3 heads respectively.
Once you count, there should be 11 outcomes with at least 2 heads in them.
The answer is 11/16.
