<u>First remove:</u>
Probability of removing a trained rat is 6/8
Probability of removing untrained rat is 2/8
Outcome is 6/8 + 2/8 = 1
<u>Second remove:</u>
Probability of picking a trained rat is 5/7
Probability of picking untrained rat is 1/7
Outcome is 6/7
<u>Third remove:</u>
Outcome is 1 (Since you can only remove a trained rat)
<u>Forth remove:</u>
Outcome is 1 (Since you can only remove a trained rat)
<u>Fifth remove:</u>
Outcome is 1 (Since you can only remove a trained rat)
Total outcome = 1 + 6/7 + 1 + 1 + 1 = 34/7 = 4(6/7)

Answer:
6,812.26
Step-by-step explanation:
I found the answer key
3 is the correct answer
u can find common ratio by dividing a specific term in GP by its preceding term. ...just as here
4/(4/3) = 3
also 12/4 = 3
also 36 /12 = 3
hence the common ratio for this GP is 3
hope it helped
