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

idk

step-by-step explanation:

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
