Question 942454: if we tossed two coins what are the probability of getting atleast one head

The two coins can land:

1. First coin heads, Second coin heads.
2. First coin heads, Second coin tails.
3. First coin tails, Second coin heads.
4. First coin tails, Second coin tails.

Only the 4th way does not have at least one head.

The other 3 do.

That's 3 ways out of 4, a probability of 3/4
