<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: 2.7 miles/hour
Step-by-step explanation:
The graph shows Elijaj travelled a total of 3 miles, and took 66 minutes to do it. Covert 66 minutes to 1.1 hours, then divide that into the mileage:
3 miles/(1.1 hours) = 2.7 miles/hr. I assume he was walking. (3 mph is a solid pace).
