Answer:
12
Step-by-step explanation:
3 times 12 is 36
The number of hours that it'll take both printers to do the job is 2.4 hours.
<em>Number of hours used by printer A = 6 hours</em>
<em>Number of hours used by printer B = 4 hours </em>
<em />
Therefore, the number of hours that'll be used by both printers will be calculated thus:
1/6x + 1/4x = 1
Using 12 as the LCM
2x + 3x = 12
5x = 12
Divide both side by 5
5x/5 = 12/5
x = 2.4 hours

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.
