Answer:
3,12,21
Step-by-step explanation:
You add 9 to the number each time so the next 3 terms will be....
-6+9 =3
3+9=12
12+9=21
The probability that all five end up in alphabetical order is; 1/120.
<h3>What is the probability that the rack ends up in alphabetical order?</h3>
To evaluate the given probability; first, the number of possible arrangements is;
17P5 = 742,560 possible arrangements.
However, the chance of an alphabetical order arrangement in each case is; 1 out of 5! possible arrangements.
Hence, we have that the number of possible alphabetical arrangement is; (1/120) × 742,560 = 6188.
Hence, the required probability is; 6188/742,560 = 1/120

Percent increase=increase/original converted to percent
increase=new-original=2.35-2.10=0.25
percent increase=0.25/2.10=0.11904=11.9%

Answer:
0.8 = 80% probability that they did in fact study for the test.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
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 question:
Event A: Passed the exam.
Event B: Studied.
Probability of passing the test:
80% of 60%(Studied).
30% of 100 - 60 = 40%(did not study). So
Probability of passing the test studying:
80% of 60%, so:
Find the probability that they did in fact study for the test with this knowledge in hand.
0.8 = 80% probability that they did in fact study for the test.
