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%

The probability that both of two tossed coins will come down heads is?
1 chance in 4
What is probability of getting all heads if 3 coins are tossed simultaneously?
There is a probability of 0.5 of heads on each coin, so there is a 1/2 * 1/2 *1/2 = 1/8 = 0.125 chance that all coins land heads. You can also express this as a percentage, 12.5% chance. The odds are 1 in 8 that this can happen.
Three fair coins are tossed at the same time What is the probability that one of the coins will show heads and the other two will show tails?
2/9
Whats the probability of getting at most one heads when two fair coins are tossed?
When two fair coins are tossed, you have the following possible outcomes: HH, HT, TH, TT. So, at most implies that you get either i) zero heads or ii) one head. From the possible outcomes we see that 3 times we satisify the outcome. Thus, probability of at most one head is 3/4.
If four coins are tossed what is the probability of tossing all heads?
The probability is 1/21/21/2*1/2=1/16, or 0.0625 or 6.25%
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.
If a coin is tossed then what is the probability that the number is 5?
Coins do not have numbers, there is only the probability of heads or tails.
Four coins tossed what is the probability of tossing all heads?
If they are fair coins, it is 1/16.
Two coins are tossed What is the probability of both coins are heads?
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
If n coins are tossed simultaneously what is the probability that they are all show heads?
(0.5)n
The probability that both of two tossed coins will come down heads is?
1 chance in 4
What is the probability that exactly two coins come up heads when four coins are tossed?
6/16 = 3/8
A coin tossed six times what is the probability of getting two heads?
1/36
When a coin is tossed three times what is the probability of getting at most two heads?
The opposite of getting at most two heads is getting three heads. The probability of getting three heads is (1/2)^2, which is 1/8. The probability of getting at most two heads is then 1 - 1/8 which is 7/8.
What is the probability of seven coins tossed simultaneously and all of them landing on heads?
It is 1/2^7 = 1/128.
What is probability of getting all heads if 3 coins are tossed simultaneously?
There is a probability of 0.5 of heads on each coin, so there is a 1/2 * 1/2 *1/2 = 1/8 = 0.125 chance that all coins land heads. You can also express this as a percentage, 12.5% chance. The odds are 1 in 8 that this can happen.
A coin is tossed 60 times It landed on heads 21 times what is the experimental probability of getting heads?
1/2
