Remember that ratios are essentially fractions without fraction bars...
If they asked to find the ration of 19.50 to 16.25 you would set them up like so....
19.50 : 16.25 -----> since fractions can be simplified so can ratios in the same manner
the ratio you would end up with is <u>6 : 5</u><u />
Ratios can be easily remembered and solved if you understand the link between them and fractions.
I hope this helps! :D

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.

Answer:
$180
Step-by-step explanation:
1. Find the perimeter: 2w + 2L
2(4) = 8 + 2(5) = 10
8 + 10 = 18 feet of fencing
2. multiply the cost per foot (10) by the number of feet (18)
10*18 = 180
Answer: 18 ft ^2
