The answer depends on what the experiment is!
Probably 3/4
The probability is 5/16.
The correct answer is 31/32 or 0.96875 because .50/2/2/2/2= 3.125%
It is approx 0.0938
The answer depends on what the experiment is!
The probability of obtaining 7 heads in eight flips of a coin is:P(7H) = 8(1/2)8 = 0.03125 = 3.1%
Probably 3/4
1/2 * 1/2 * 1/2 = 1/8 = 12.5%
The probability is 5/16.
The correct answer is 31/32 or 0.96875 because .50/2/2/2/2= 3.125%
7*(1/2)7 = 7/128 = 5.47% approx.
It is approx 0.0938
About a 1 in 16 chance of getting a coin to land on heads 4 times in a row.
The probability of tossing two heads in two coins is 0.25.
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
It's difficult to think of a real event to which an exact probability can be assigned. We say that flipping a coin yields 'heads' with probability 1/2 but we do not know that definitely. The only way of assigning a probability in the sense of numbers of heads versus total numbers of flips is by experiment. (Be aware though that there are other interpretations of the word probability.) If I were to flip a coin 500 times and obtained 249 heads then the experimental probability of obtaining a head would be 249/500 or 0.498.
