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.
50%

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.
1/4 if they are tossed only once.
