Abox contains 3 coins. one coin has 2 heads and the other two are fair. a coin is chosen at random from the box and flipped. if the coin turns up heads, what is the probability that it is the two-headed coin? is the answer 1/3? was the answer intuitive?

Our required probability is

Step-by-step explanation:

Since we have given that

Number of coins = 3

Number of coin has 2 heads = 1

Number of fair coins = 2

Probability of getting one of the coin among 3 =

So, Probability of getting head from fair coin =

Probability of getting head from baised coin = 1

Using "Bayes theorem" we will find the probability that it is the two headed coin is given by

Hence, our required probability is

No, the answer is not

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
