3/8 * * * * * That is the probability of getting EXACTLY 1H. The prob of getting one (or more) head is 7/8

The probability of tossing two heads in two coins is 0.25.

50%

1/2

6/16 = 3/8

3/8

The probability is 0.375

The answer depends on what a winner is: 1 H?, a run of 3 H?If the winner is one H, the probability of getting exactly one winner - no more no fewer - is 5/32.

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.

It is 0.00540 approx.

The probability is 1/16.

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!

0.5

1/4 if they are tossed only once.

Coins do not have numbers, there is only the probability of heads or tails.

The sample space is 23 or 8; which can be listed out as: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. There are 2 of the 8 that have exactly 2 heads; so the probability of exactly two coins landing on heads is 2/8 or 1/4.

If they are fair coins, it is 1/16.

The probability is 3/4.

50/50

The answer depends on how many coins were tossed.

No. It is 1/2.

The probability of getting 8 heads out of 10 tosses is (10C8)(1/2)^8 (1/2)^2 = 45 / 1024 = 0.0439. It is assumed that the probability of getting a head in a single toss is 1/2. 10C8 = 10 x 9 / 1 x 2 = 45

The probability that both coins are heads is the probability of one coin landing heads multiplied by the probability of the second coin landing heads: (.5) * (.5) = .25 or (1/2) * (1/2) = 1/4
