First find 2 to the power of 2. Which is multiplying 2 by its self so 4x.
Then add the 4x to 7x which is 11x
Then since 4 doent have an x it cant be combined so thats the answer: 11x + 4
It would be 3 times the sum of x and seven plus 10. This is because first you would would add 7+x (7x) and multiply it by 3. And then add on 10.

Answer:
A) 0.1538
Step-by-step explanation:
4 members are going to be chosen:
M1 - M2 - M3 - M4
We have to find the probability that for each member, one without experience is chosen. There is no replacents.
Initially, we have 15 students, of which 10 have none experience. So the probability that M1 is chosen as a student with no experience is
.
Then, there are 14 students, of which 9 have no experience. So the probability that M2 is chosen as a student with no experience is
.
For the third member, there are 13 students, of which 8 have no experience. So the probability that M3 is chosen as a student with no experience is
.
For the last member, there are 12 students, of which 7 have no experience. So the probability that M4 is chosen as a student with no experience is
.
What is the probability that none of the members chosen for the team have any competition experience?
This is

The correct answer is:
A) 0.1538
