What is the probability that exactly two coins come up heads when four coins are tossed?
6/16 = 3/8
What is the chance that that 2 flipped coins both come up heads?
The probability that 2 flipped coins both come up heads is 0.52 or 0.25
If you flip two coins the probability that both will come up heads is?
one fourth
The probability that both of two tossed coins will come down heads is?
1 chance in 4
What is the probability of getting 2 heads when you toss three coins?
If you mean 'at least' 2 heads, the probability is 50%. If you mean exactly 2, the probability is 3/8, or 37.5%. There are 3 independent coin tosses, each of which is equally likely to come up heads or tails. That's a total of 2 * 2 * 2 or 8 possible outcomes (HHH, HHT, HTH, etc.). Of these, 4 include 2 or 3 heads, which is half of 8. Only 3 include exactly 2 heads, so the probability of that is 3/8.
If You flip 9 fair coins Amazingly the first 8 flips all come up heads What is the probability that the final flip will be a head too?
1/2 apex It does not matter what each prior flip's result was. Each flip has a probability of 0.5 heads or tails. Coins do not have "memory".
If you flip 10 pennies all at the same time, what is the probability that exactly 3 will come up heads and 7 will come up tails?
It is 0.1172
What is the probability of getting two heads one tail when you spin 3 coins?
First work out the probability of the first two coins being heads and then the last being tails. This is 1/2 x 1/2 x 1/2 which is 1/8 The next step is to find out how many different orders the coins can come in. In this case there are 3 possible orders (HHT, HTH, and THH). Multiply this by the above probability and you get 3/8. Therefore the probability of getting two heads and one tail is 3/8
What is the probability of tossing seven coins at one time and having 7 of them come up heads?
The probability would be once in 128 attempts. You don't have to toss seven coins simultaneously. the 7 tosses just have to be independent of one another.
Probability of getting 2 heads out of 4 coins when tossed?
For exactly two; we take the chance that for the first two coins come out heads and the second 2 come out tails. and then we multiply by the number of different possibilities. (i.e it could be the first and third or the first and fourth). so we get .5*.5*.5*.5*6=.375=37.5%if you want 2 or greater. the answer by similar logic is .5625 or 56.25%
If you flip 10 pennies all at the same time what is the probability that exactly 3 will come up heads and 7 will come up tail?
10C3(0.5)^10
What is the probability that the next coin flip will come up heads?
If it is a fair coin then the probability is 0.5
