Answer:
C) S = {F, PF, PPF, PPP}
Step-by-step explanation:
For this case, we know that a person is trying to gain access to a bank vault and needs to go through 3 security doors, and we know that if the person does not pass a door, then he/she has no other attempts. We denote P= Successful pass , F= Failed pass
And we are interested on the sample space, we need to remember that the sample is the set with all the possible values for an experiment.
For this case the person can fail at the 1,2 or 3 try
For the case that fails at the 1 try we have F
For the case that fails at the 2 try we have PF
For the case that fails at the 3 try we have PPF
And the last option is that the person not fails at any try and we have PPP
So then the sample space would be given by:
C) S = {F, PF, PPF, PPP}
The very first statement is true. No need to worry about the rest!
Try it out. If you have 9 cups and I have 6... and we both take 3 more... now you have 12 and I have 9. You still have more.
If I have 10 dollars in the bank and you have 5 and we both add -3 to our account by paying a monthly fee - I will have 7 and you will have 2. I have five more than you in both examples.
Adding the same amount to both sides does not change the solution.
Answer:
True
Step-by-step explanation:
Take out a graph paper and try to rotate (-2,-5) counterclockwise at 270° (three times 90°) and it will show that the point lands at (-5,2).
Hope this helps
