If nine fair coins are tossed what is the probability of obtaining at least one head and at least one tail using the complement formula?
255/256 (complement formula)
If three fair coins are tossed in how many ways can at least one head be obtained?
Ignoring the very small possibility that a coin tossed will land on its edge and stay there, I'll assume each coin can land either Head or Tails. The reverse of the condition "at least one Head" is "no Heads" Thus the number of ways of at least one Head is the same as the total number of ways less the number of way of no Heads. There are 2 × 2 × 2 = 2³ = 8 possible ways the three coins can land. Of these there is only 1 way which shows no Heads: TTT Thus there are 8 - 1 = 7 ways that at least one Head shows You could list all the possible ways that at least one head shows (which are: HTT, THT, TTH, HHT, HTH, THH, HHH - 7 of them), but the "subtractive" method above is much quicker and easier and less prone to error in the listing.
How many possible outcomes for flipping 2 coins?
Assuming the coins are fair, two-sided coins, and landing on their sides is not an option, there are four possible outcomes if you consider coin a having a head and coin b having a tail being a different instance from coin a being a tail and coin be having a head. Here they are; Coin A | Coin B Heads | Tails Heads | Heads Tails....| Heads Tails....| Tails
What coins do not have head on either side?
A trick coin that you buy at a magic shop, I reckon.
What are the odds in favor of getting at least one head in 3 consecutive flips of a coin?
>>> 1:7 (or, if you like probability, 87.5%)I disagree. There are four possible combinations of three tosses (where order does not matter):HHHHHTHTTTTTThree of these combinations will show at least one head - only by throwing three tails will you not throw at least one head.Thus, the probability of throwing at least one head in three flips is 75%.
Getting at least one head when tossing eight fair coins?
Is possible.
If nine fair coins are tossed what is the probability of obtaining at least one head and at least one tail using the complement formula?
255/256 (complement formula)
What is the probability of flipping a head when you roll a coin 3 times?
If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8If it is a fair coin, the probability of getting at least one Head from 3 flips is 7/8
What is the probability of getting at least one head if two coins were flipped?
Let put the question in an other way : obtaining at least one head is the contrary of obtaining two tails at the same time. The probability to obtain one tail with first coin is 1/2, the probability to obtain one tail with the other is also 1/2, so the probability to obtain one tail on each coin is 1/2x1/2 = 1/4 Thus the probability to obtain at least one head is 1-1/4=3/4
You toss 3 coins What is the probability that you get exactly 2 heads given that you get at least one head?
you toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one head?
Probability of getting one head and two tails on a toss of three fair coins?
50%
When tossing 3 coins simultaneously find the probability that at least 1 head is showing?
No matter how many coins are thrown, the possibility of having AT LEAST ONE 'head' is 50%. This changes if you specify the number of 'heads' that must be shown.
When tossing 5 coins simultaneously can you find the probability that at least 1 head is showing?
Probability not at least 1 head showing is when all 5 coins are tails: (1/2)5=1/32 Therefore probability at least 1 head is showing is 1-1/32=31/32
Three fair coins are tossed- whats the probability of tossing at least one head?
The chance for each toss is 1/2. The chance of all three flips being tails is 1/2 * 1/2 * 1/2 = 1/8. So the probability of at least one head is 7/8.
A fair nickel and a fair dice are tossed once outcomes match when both coins land on heads or both coins land on tails What is the theoretical probability of a match?
The probability of 2 coins both landing on heads or both landing on tails is 1/2 because there are 4 possible outcomes. Head, head. Head, tails. Tails, tails. Tails, heads. Tails, heads is different from heads, tails for reasons I am unsure of.
When tossing 4 coins simultaneously find the probability that at least 1 head is showing?
It is 15/16.
What is the probability of at least one head?
If you throw a single fair coin multiple times, the probability of getting NO head is:For 1 throw: 1/2 For 2 throws: 1/2 squared = 1/4 For 3 throws: 1/2 cubed = 1/8 etc. The probability of getting AT LEAST ONE head is the complement; for example, for 3 throws, it would be 1 minus 1/8.
