Answer:

Probability: $\frac{1}{2}$ = 0.5 = 50%

Step-by-step explanation:

The following possibilities are that the coin has double heads or is a regular coin with both tails and heads. Seeing as the coin landed on heads, there are only two possible out comes for the other side of the coin

The other side is either Heads or Tails. That gives us a 50% chance of the other side being tails.

$\frac{1}{2}$ = 0.5 = 50%
