The area of a circle = Pi(3.141592) x R (radius-half of diameter)^2
A=113.1
Using conditional probability, it is found that there is a 0.1 = 10% probability that the chosen coin was the fair coin.
Conditional Probability
In which
- P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem:
- Event A: Three heads.
- Event B: Fair coin.
The probability associated with 3 heads are:
out of 0.5(fair coin).- 1 out of 0.5(biased).
Hence:

The probability of 3 heads and the fair coin is:

Then, the conditional probability is:

0.1 = 10% probability that the chosen coin was the fair coin.

Step-by-step explanation:
3.7-1
point in mathematics mean multiplication
so
3*7-1
21-1
20
The first is 97.0 mL
The second is 106.9 mL
The third is 24.0 mL
I think the last is 37.0 but I can barely see the numbers
