You flip the same coin 75 times Amazingly the first 74 flips all come up heads How probable is it that this is not a fair coin?
Highly probable - APEX :)
What is the probability that a single coin flip will come up heads on the first two flips?
The probability of heads on the first flip is 50%.The probability of heads on the second flip is 50%.The probability of both is (50% x 50%) = 25% .=========================================Another way to look at it:Two tosses can come up in four different ways:H HH TT HT TOnly one of these . . . H H . . . counts as success.1 out of 4 = 25% .
If you flip a coin and toss a one to six What is the probability of getting three heads?
The odds of flipping a coin and having it come up heads three times in a row is (1/2)*(1/2)*(1/2)=(1/8) or 12.5% ■
A coin is tossed twice If heads comes up either time you get 2 dollars If heads does not come up you lose 4 dollars What is the expected value of this game?
There is a .25 chance that no heads will come up. (1/2*1/2=.25) Therefore, there is a .75 chance that one or more heads will come up. Value of game = .75*$2-.25*$4=$1.5-$1=$.50 Over time, you should come out ahead.
What is the probability that you flip a head after you flipped 100 coins and 87 were heads and 13 were tails?
50% Every time you flip a coin, there is a 50% chance it will come up heads and a 50% chance it will come up tails, no matter how many times you have already flipped it, and no matter what the results were of previous flips.
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
What are the odds if a coin is tossed 3 times and the out come is heads?
The answer depends on "the outcome is heads HOW MANY TIMES!"
The probability that a coin flip will come up heads?
Assuming: (a) the coin is fair (each side is the same exact weight) (b) the chance of the coin landing in its side is eliminated (c) the coin is not acted on by any forces such as magnetism The chance of the coin displaying heads is 50%, or 1/2.
What is the probability that if you flip the coin twice you come up with heads once and tails once?
It is 1/2.
When a coin is flipped what is the probability that it will come up tails?
The side heads is slightly heavier giving it a greater likely hood of landing on tails.

If you flip a a coin 20 times what is the probability that the coin will land on heads?
There is a fifty percent chance of the coin landing on "heads" each time it is flipped.However, flipping a coin 20 times virtually guarantees that it will land on "heads" at least once in that twenty times. (99.9999046325684 percent chance)You can see this by considering two coin flips. Here are the possibilities:Heads, heads.Heads, tails.Tails, tails.Tails, heads.You will note in the tossing of the coin twice that while each flip is fifty/fifty, that for the two flip series, there are three ways that it has heads come up at least once, and only one way in which heads does not come up.In other words, while it is a fifty percent chance for heads each time, it is a seventy five percent chance of seeing it be heads once if you are flipping twice.If you wish to know the odds of it not being heads in a twenty time flip, you would multiply .5 times .5 times .5...twenty times total. Or .5 to the twentieth power.That works out to a 99.9999046325684 percent chance of it coming up heads at least once in the twenty times of it being flipped.
Are events and its complement mutually exclusive?
Yes, they cannot happen at the same time. If you flip a coin heads and tails can not come up at the same time.
What does it mean to say that the chances of getting a head when a coin is tossed are one-half?
It means that if the coin were tossed an infinite number of times, half of the tosses would come up heads and half would be tails.
