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 :)
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% ■
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% .
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.
