What is the probability of getting a head when spinning 2 coins?
Just one head = 2/4 = 1/2
Probability of getting one head and two tails on a toss of three fair coins?
50%
10 coins are tossed once .The probalilty of getting exactly eight heads is?
The probability of getting exactly eight heads when tossing 10 coins once can be found using the binomial probability formula. Assuming a fair coin, the probability of getting a heads is 1/2. Plugging in the numbers, the probability of getting exactly eight heads is (10 choose 8) * (1/2)^8 * (1/2)^2 = 45/1024, which is approximately 0.04395.
What is the probability of flipping 91 coins and getting a head 91 times in a row?
The probability of flipping 91 coins and getting a head 91 times in a row is 1/291 or (1/2)91 or 4.039E-28. The (1/2)91 is when there is exactly 91 coin tosses or n = 91. As the number of trials increases so does the probability of at least 1 run of length 91. The average number of coin flips to see 91 in a row is 4.951760157141521e+27
What is the probability of getting one head if 3 coins are tossed?
3/8 * * * * * That is the probability of getting EXACTLY 1H. The prob of getting one (or more) head is 7/8
Probability of getting 1 head tossing two coins?
By tossing two coins the possible outcomes are:H & HH & TT & HT & TThus the probability of getting exactly 1 head is 2 out 4 or 50%. If the question was what is the probability of getting at least 1 head then the probability is 3 out of 4 or 75%

Two coins are tossed what is the probability of getting a head?
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!
What is probability of getting one head if you toss four coins simultaneously?
one out of four
What is the probability of getting a head when spinning 2 coins?
Just one head = 2/4 = 1/2
Probability of getting one head and two tails on a toss of three fair coins?
50%
You flip 3 coins Use a tree diagram to calculate the probability that you get exactly 1 head?
3/8

What is the probability of flipping three coins and getting one head followed by one tail by one head?
1/8 or 12.5%
What is the probability of flipping 91 coins and getting a head 91 times in a row?
The probability of flipping 91 coins and getting a head 91 times in a row is 1/291 or (1/2)91 or 4.039E-28. The (1/2)91 is when there is exactly 91 coin tosses or n = 91.

What is the probability of tossing three coins and having all of them show tails?
When we toss a coin getting head or tail have equal probability of 50% - that is, out of the two possible outcomes getting the specified one becomes 1/2 probability. When we toss three coins, the probability of getting all the coins showing tails is given by (1/2) * (1/2) * (1/2) equal to 1/8 or 12.5 % chance. Alikban
