lets get some facts
odds of head on 1 coin 50% or evens
odds of no head 50% or evens
the possible results vary from 1 coin to 2 coins.
1 coin has 2 results heads or tails
2 coins have 4 results. heads heads, tails tails, tails heads, heads tails. each outcome has a probability of 25%. for the question we remove the heads and tail probability and we have 2 outcomes with heads and one without. so 2 to 1 chance or 33.3333 recuring chance.
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!
50/50
Sample space for two coins tossed is: HH HT TH TT Therefore at most one head is HT TH TT or 3/4 or 0.75.
It is 0.75
the probability of getting one head and one tail on three flips of a coin is 1/9
3/8 * * * * * That is the probability of getting EXACTLY 1H. The prob of getting one (or more) head is 7/8
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!
50/50
Sample space for two coins tossed is: HH HT TH TT Therefore at most one head is HT TH TT or 3/4 or 0.75.
The probability is 3/4.
The probability is 50-50.
The probability is 1/4
It is 0.75
285 out of 500
obviously it is a 50-50 chance
1/2 or 50% (1/8 prob of 0H + 3/8 prob of 1H)
Assuming that it is a fair coin, the probability is 0.9990
