total events of tossing coins twice = {HH,HT,TH,TT} Favorable events = {HH,HT,TH} Thus the probability that the first or the second toss is heads = probability of (HH+HT+TH)=0.6*0.6+0.6*0.4+0.4*0.6 = 0.84. Thus Option C is correct 0.84. acobdarfq and 2 more users found this answer helpful.

Suppose I have an unfair coin, and the probability of flip a head (H) is p, probability of flip a tail (T) is (1-p). If I flip the coin 6 times, wondering if the probability of HTT???, and the probability of THT???, and the probability of TTH??? are the same? Suppose each flip is independent. ? means do not care if head or tail. Thanks.

When you know the chance of a particular event, then you can make predictions about the probability of it happening. A fair game is a game in which there is an equal chance of winning or losing. We can say that if a game is fair then the probability of winning is equal to the probability of losing.

For a fair coin, the probability of getting 20 heads in 20 flips is $$2^{-20}$$, which is less than 1 in a million. This is small, so the coin is likely unfair. For a fair coin, the probability of seeing at least 12 heads is approximately 0.25. As 0.25 is not small, we lack significant evidence that the coin is unfair.
An unfair coin has a probability P*P*(1-P) = 2*(P^2) - (P^3) of going HHT. Integrating across P from 0 to 1, you also get 1/8. Therefore, whether the coin was biased or not, you had an even chance when...

Make a Fair Coin from a Biased Coin January 3rd, 2018. If we have a biased coin, i.e. a coin that comes up heads with a probability not equal to $$\frac{1}{2}$$, how can we simulate a fair coin? The naive way would be throwing the coin 100 times and if the coin came up heads 60 times, the bias would be 0.6.
