Explanation

Probability is simply the ratio of

[tex]P=\frac{number\text{ of possible outcomes}}{number\text{ of total outcomes}}[/tex]

The number of total outcomes is 16 as given in the image

The number of possible outcomes is the number of having at least 2 heads is shown below

Thus, we have the probability as
