The chance of one tail (on a fair coin - i.e. it's not weighted or biased) is 0.5
Using the AND rule, which means the probability of two things BOTH happening means the two probabilities are multiplied. So the chance of a tail on coin 1 AND a tail on coin 2 is 0.5 x 0.5 = 0.25
The chance of 3 tails 0.5 x 0.5 x 0.5 = 0.125
The chance of 4 tails 0.5 x 0.5 x 0.5 x 0.5 = 0.0625
So your answer is 0.0625

What is a 1904 Morgan Dollar worth?
August 10, 2009 The 1904 Morgan Dollar was produced at 3 US mints: Philadelphia which is shown as 1904-P in this list, New Orleans which is shown as 1904-O in this list and San Francisco which is shown as 1904-S in this list. To determine which coin you have it is necessary to locate the mint mark. This mark consists of a small letter located on the reverse [tails] side of the coin just above the letters "DO" in the word "DOLLAR". The letter "O" is for New Orleans. The letter "S" is for San Francisco. If there is no letter the coin was minted at Philadelphia. The circulated and uncirculated values for these coins are shown in the following list: Circulated Grades.........1904-P.....................1904-O................1904-S G4...................................$20...........................$18.....................$35 F12..................................$26...........................$21.....................$52 EF40................................$32...........................$24.....................$245 AU55................................$37...........................$27.....................$625 Uncirculated GradesMS62.................................$140.......................$38.......................$2,400 MS63.................................$265.......................$50.......................$3,800 MS65.................................$3,250.....................$160.....................$10,500
What is the probability of tossing 3 coins and getting 3 tails?
It is (1/2)3 = 1/8
What is the probability of tossing a coin and getting an even number?
Zero. Since coins land on Heads or Tails and not numbers.
Tossing 4 coins and getting tails each time?
The probability for that is (1/2)4 = 1/16.
What is the probability of tossing four coins and getting tails on all four?
Assuming it is a fair coin, the probability is 1/24 = 1/16.
What is sample space for tossing 2 coins?
The sample space for tossing 2 coins is (H = Heads & T = Tails): HH, HT, TH, TT
What is the probability of tossing a coin and getting a tails?
50% chance.
What is the number of possible outcomes when tossing 4 coins at once?
When tossing 4 coins at once, each coin has 2 possible outcomes: heads (H) or tails (T). Therefore, the total number of possible outcomes can be calculated as (2^4), which equals 16. This means there are 16 different combinations of heads and tails when tossing 4 coins.
What is the probability of tossing three coins and having exactly two of them show tails?
2 out of 8
How many possible outcomes when tossing 3 coins?
three heads two head, one tails one heads, two tails three tails
What is the experimental probability of getting tails on a coin toss after tossing it 100 times and getting tails 60 times?
It is 60/100 = 0.6
What is the probability of tossing a coin 5 times and getting all tails?
The probability of tossing a coin 5 times and getting all tails is:P(TTTTT) = (1/2)5 = 0.03125 ≈ 3.13%
What is the probability of tossing seven coins and getting 6 heads?
The probability of getting only one tails is (1/2)7. With seven permutations of which flip is the tails, this gives a probability of: P(six heads in seven flips) = 7*(1/2)7 = 7/128
