You’re friends with two twins: Ella and Emma. They are identical in every way as far as you can tell, except one. You can tell them apart when playing rock-paper-scissors; Ella beats you one in three times (as would be expected), but Emma somehow always guesses what you will do and beats you in every game. One day, you run into a random twin and play rock-paper-scissors five times with her; you lose every game. What is the probability that it’s Emma you encountered?

A student's course grade is based on one midterm that counts as 10% of his final grade, one class project that counts as 5% of his final grade, a set of homework assignments that counts as 45% of his final grade, and a final exam that counts as 40% of his final grade. His midterm score is 74, his project score is 86, his homework score is 91, and his final exam score is 71. What is his overall final score? What letter grade did he earn (A, B, C, D, or F)? Assume that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B, and so on. His overall final score is. (Type an integer or a decimal rounded to one decimal place as needed.)
If you add the age of six people (Alice, Barb, Carol, Dean, Eric, and Fred), the total is 92. Alice is twice the age of Carol. The total age of Barb and Eric equals that of Fred. The total age of Alice and Carol equals the total age of Barb and Fred. Carol is 8 years younger than Fred. If you subtract the age of Eric and Carol from Dean the result is 10.
