4) You want to know if an octopus (octopi are very intelligent!) can tell the difference between circles and rectangles. You provide each octopus with one circular disk and one flattened rectangle. You hide food under the circle. After several trials, you then count how many times the octopus picks up the circle and how many times it picks up the rectangle. You get the following results: Circles: 27 Rectangles: 13 Can the octopus tell the difference between circles and rectangles? (Hint: if the octopus can't tell the difference, what's the probability that he/she will pick a circle?)

Darnell and Jake are playing a game they made up which includes throwing darts at this target. The point values for each region of the target are shown. The radius of the 50-point region is 3 inches. The width of each of the other regions is 4 inches. 5 concentric circles where each circle contains values from 10, 20, 30, 40 and 50. Darnell and Jake are currently tied in their game, and Jake has to choose one of these options: Option 1: He can accept the tie, and the game is over. Option 2: He can make one more throw. Jake wins if he earns at least 30 points on the throw, but he loses if he earns less than 30 points. Complete each part of this task to determine which option Jake should choose. Part A Describe the process you could use to find the probability that Jake will earn at least 30 points on a throw, given that he hits the target? Note: Assume that it is equally likely that he will hit any region in the target.

The game of baseball darts is played on a square board marked like a baseball diamond. Each side of the diamond is 15 inches long. The bases are 3.5 inch squares in each corner. There is a home-run circle in the center with a diameter of 2 inches. “Hits” are made by landing on the bases or in the home-run circle. Landing anywhere else in the diamond is considered an “out”. Mona is blindfolded and throws a dart which lands on the board in a random manner. What is the probability that she is “out”?
