Answer: 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 
Answer:
Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
7-24-25
7² + 24² = 25²
49 + 576 = 625
625 = 625
9-40-41
9² + 40² = 41²
81 + 1600 = 1681
1681 = 1681
Answer:

Step-by-step explanation:
Area of circle:

By using the area of a circle, we can get the area of a semicircle:

Let's convert the mixed fraction to an improper fraction and then a decimal:
=
= 
Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

Now we have the radius, so we can plug in our values and find the area:


-2 is the answer because you do the change of y over the change of x.
