The probability that of getting a head when a fair coin is tossed is 0.5.
The events of tossing a coin are independent. This means that the probability of getting head or tail when a coin is tossed is not dependent on the outcome of the previous toss.
Hence, on the fifth trial, the probability that head appears is 0.5
option C

Suppose that a coin is tossed three times. We assume that a coin is fair, so that the heads and tails are equally likely. Probability that two heads are obtained in three tosses given that at least one head is obtained in three tosses is ___________ Probability that that one head is obtained in three tosses given that at most one head is obtained in three tosses is ____________ at least one means one or more, at most one means...

a. Suppose that a fair coin is tossed 15 times. If 10 heads are observed, determine an expression / equation for the probability that 7 heads occurred in the first 9 tosses. b. Now, generalize your result from part a. Now suppose that a fair coin is to be tossed n times. If x heads are observed in the n tosses, derive an expression for the probability that there were y heads observed in the first m tosses. Note the...

A coin flip: A fair coin is tossed three times. The outcomes of the three tosses are recorded. Round your answers to four decimal places if necessary. Part 1 of 3 Assuming the outcomes to be equally likely, find the probability that all three tosses are "Heads." The probablility that all three tosses are "Heads" is 0.1250 Part: 1/3 Part 2 of 3 Assuming the outcomes to be equally likely, find the probability that the tosses are all the same....
