It's important to study and study. I recommend studying the homework or study sheet the day before the test. Most likely the teacher has added a similar problem on to the test. Add a friend to help you study.
To make it fun, buy candy and quiz yourself or friends!
If you get a problem right, them give yourself candy.
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%.
