Need help with question #4. I have already done #3 so do not need to do that.

3) Mendelian genetics predict that in Labrador retrievers (a type of dog), 25% should have a brown coat color if both parents are heterozygous (the rest are black). You mate two parents and get a litter of 8 puppies. Calculate the following: a) The probability of 5 black puppies. b) The probability of 5 brown puppies. c) The probability that 50% of the puppies will be brown. (Comment: You do not need to know anything about genetics to solve this problem. If you're trying to do things like use punnet squares, you're doing things the wrong way.) 4) Refer to problem 3. Suppose you only had 3 puppies. Calculate the probability of every possible outcome (you need to do four calculations)
