When two coins are tossed simultaneously, what are the chances of getting at least one tail?

Answer: Option C

At least one tails means one tails or both tails
Let us see what the possible outcomes are when two coins are tossed simultaneously
We can get,
1. Heads and Heads
2. Heads and Tails
3. Tails and Heads
4. Tails and Tails
So we have total = 4 outcomes
Out of them, 3 have tails in it
Chances of at least 1 tails = $$\frac{3}{4}$$
