When two fair coins are tossed, you have the following possible outcomes:
HH, HT, TH, TT.
So, at most implies that you get either i) zero heads or ii) one head.
From the possible outcomes we see that 3 times we satisify the outcome.
Thus, probability of at most one head is 3/4.
possible
The probability is 3/8 = 0.375
3/8
is it 50% or 100% dang, i just confused myself. what if you toss 3 coins all at the same time... what's the probability of getting a head then, is it > 100% ? Doh!
The probability of getting two tails in the first two is 1/4. And it does not matter how many more times the coins are tossed after the first two tosses.
The probability of tossing two heads in two coins is 0.25.
1/2
possible
50%
The probability is 3/8 = 0.375
3/8
3/8 * * * * * That is the probability of getting EXACTLY 1H. The prob of getting one (or more) head is 7/8

The probability is 1/16.
The probability of getting two tails in the first two is 1/4. And it does not matter how many more times the coins are tossed after the first two tosses.
Coins do not have numbers, there is only the probability of heads or tails.
