Answer:
The probability that our guess is correct = 0.857.
Step-by-step explanation:
The given question is based on A Conditional Probability with Biased Coins.
Given data:
P(Head | A) = 0.1
P(Head | B) = 0.6
<u>By using Bayes' theorem:</u>
![P(B|Head) = P(Head|B) \times \frac{P(B)}{P(Head)}](https://tex.z-dn.net/?f=P%28B%7CHead%29%20%3D%20P%28Head%7CB%29%20%5Ctimes%20%5Cfrac%7BP%28B%29%7D%7BP%28Head%29%7D)
We know that P(B) = 0.5 = P(A), because coins A and B are equally likely to be picked.
Now,
P(Head) = P(A) × P(head | A) + P(B) × P(Head | B)
By putting the value, we get
P(Head) = 0.5 × 0.1 + 0.5 × 0.6
P(Head) = 0.35
Now put this value in
, we get
![P(B|Head) = P(Head|B) \times \frac{P(B)}{P(Head)}](https://tex.z-dn.net/?f=P%28B%7CHead%29%20%3D%20P%28Head%7CB%29%20%5Ctimes%20%5Cfrac%7BP%28B%29%7D%7BP%28Head%29%7D)
![P(B|Head) = 0.6 \times \frac{0.5}{0.35}](https://tex.z-dn.net/?f=P%28B%7CHead%29%20%3D%200.6%20%5Ctimes%20%5Cfrac%7B0.5%7D%7B0.35%7D)
![P(B|Head) = 0.857](https://tex.z-dn.net/?f=P%28B%7CHead%29%20%3D%200.857)
Similarly.
![P(A|Head) = 0.857](https://tex.z-dn.net/?f=P%28A%7CHead%29%20%3D%200.857)
Hence, the probability that our guess is correct = 0.857.
The answer is 20. You use 20 markers for it all.
Answer:
36 meters^3
Step-by-step explanation:
Formula: Bh
B=Base area
h=height
to find the base area, multiply 2 and 6
2x6 = 12
B=12
and the height is given, so just insert your numbers into the formula
12x3=36
given: s is the midpoint of rt
definition of midpoint: rs st
given: st xy
transitive property of congruence: rs xy
