Question

We have three coins: one with heads on both faces, the second with tails on both faces, and the third a regular one. We choose one at random, toss it, and the outcome is heads. What is the probability that the opposite face of the tossed coin is tails?

Answer 1

Answer:

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

Step-by-step explanation:

Based on the question one coin is chosen at random and tossed. That coin then lands and is heads. Since the coin landed on heads we can eliminate the possibility of the coin that was chosen being the coin with double tails.

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%
