The experimental probability is given by the next equation:

[tex]P=\frac{#\text{ of favorable outcomes}}{Total\text{ \# of outcomes}}[/tex]

Where :

# of favorable outcomes is given by the times when landed on tails. Then,

# of favorable outcomes = 20 times

And the total # of outcomes is the total times that Mandy flipped the coin.

Then,

Total # of outcomes = 50 times

Replace using the probability formula:

[tex]P=\frac{20}{50}[/tex]

Simplify it:

[tex]P=\frac{2}{5}[/tex]

The correct answer is option B.
