Answer:
The probability that the two rats are from the first litter is 14.28%, and the probability that the two rats are from the second litter is 34.28%.
Step-by-step explanation:
Since a cage holds two litter of rats, and one litter comprises one female and five males, while the other litter comprises seven females and two males, and a random selection of two rats is done, to find the probability that the two rats are from the same litter the following calculation must be performed:
6/15 x 5/14 = 0.1428
9/15 x 8/14 = 0.3428
Therefore, the probability that the two rats are from the first litter is 14.28%, and the probability that the two rats are from the second litter is 34.28%.
You would divide 1350 by 47 to find our how many strings of lights she would need.
1350 / 47 = 28.7234
note that IF you choose 28, you would run short because it would not be enough to cover all of that edge.
so you would need to round up to 29
therefore our answer would be D)29 strings of lights.
