There are four different ways that two coins can land:
T T
T H
H T
H H.
Only one of them is two heads, so if the coins are fair, then
the probability is 1/4 = 25% .

If you toss 2 coins what is the probability of getting two heads?
1:4
If you toss three coins what is the probability that two coins will be heads up?
Possibilities: HHH, HHT, HTH, THH, HTT, THT, TTH, TTT. There are 3 chances out of 8 that there will be two heads and one more that there will be AT LEAST two heads.
What is the probability of getting a tail if a coin tossed once?
Since the coin only has two sides, the probability of getting either heads or tails in any one toss is 1 in 2, or 50%. 50 precent chance. Everytime you toss it, 50 percent.
What is the probability of getting two heads in a row followed by three tails in a row?
If you toss a coin often enough, it is a certainty, so that the probability = 1. The probability of that outcome in the first five tosses of a coin is (1/2)5 = 1/32.
What is the probability that you toss a head or a tail?
Assuming a two-sided coin, and that you make the the toss, the probability of tossing a head or a tail is 100%. The probability of tossing a head is 50%. The probability of tossing a tail is 50%.
What is the probability that they you will get two heads when you toss two coins?
If you toss them enough times, the probability is 1. For just one toss the probability is 1/4.
What is the probability of getting two heads when you toss two coins?
If you toss the coins once only, it is 1/4.

What are the chances you are going to toss 2 pennies 20 times how many times do you expect the 2 pennies will come up 2 heads?
Each time you toss two pennies, there are four ways they can land: H H H T T H T T One of the four ways is (Heads - Heads), so the probability of 2 heads is 1/4 or 25% . If the pennies are 'fair' (not loaded), and you toss them a large number of times, you should expect 2 heads roughly 1/4 of the time. Out of 20 tosses, that's 5 times. But don't bet on it.
What is the probability that a coin that is tossed 10 times what is the probability of it landing on heads 10 times?
The probability is 0.09766%.Each toss has a ½ chance to be heads. To combine probabilities use multiply them. So the probability to get two heads out of two tosses is ½ * ½, and three heads out of three tosses is ½ * ½ * ½. So the exact answer is 0.5^10
What is a probability of tossing exactly two heads?
Coin tosses are what we call Independent Events, meaning that the results of one toss have no effect on the next toss or any thereafter. Therefore the probability of each toss is 1/2. If, however, you want to know the probability of tossing two coins, and each coin landing heads-up, you simply multiply their probabilities together, resulting in 1/4.
What is the probability that exactly two times head are being tossed?
The answer depends on how many times the coin is tossed. The probability is zero if the coin is tossed only once! Making some assumptions and rewording your question as "If I toss a fair coin twice, what is the probability it comes up heads both times" then the probability of it being heads on any given toss is 0.5, and the probability of it being heads on both tosses is 0.5 x 0.5 = 0.25. If you toss it three times and want to know what the probability of it being heads exactly twice is, then the calculation is more complicated, but it comes out to 0.375.
If you toss three coins what is the probability that two coins will be heads up?
Possibilities: HHH, HHT, HTH, THH, HTT, THT, TTH, TTT. There are 3 chances out of 8 that there will be two heads and one more that there will be AT LEAST two heads.

What is the probability of getting 2 heads when 2 coins are tossed?
The probability of tossing two heads in two coins is 0.25.
