answer Review& Preview1.2.1SearchCC Geometry1-55.Probability is used to make predictions. See the Math Notes in this lesson for more details. Whenever the outcomes are equally likely,the probability in general is:P(success)number of successtotal number of possible outcomesFor example, if you were to reach into a bag with 16 total shapes, four of which have right angles, and randomly pull out a shape, youcould use probability to predict the chances of the shape having a right angle.number of successP(right angle):total number of possible outcomes4 shapes with right angles16 total shapes= = 0.25 = 25%%3D%3DThe example above shows all forms of writing probability: (read "4 out of 16") is the probability as a ratio, 0.25 is its decimalform, and 25% is its equivalent percent. What else can probability be used to predict? Analyze each of the situations below:a. The historic carousel at the park has 4 giraffes, 4 lions, 2 elephants, 18 horses, 1 monkey, 6 unicorns, 3 ostriches, 3 zebras, 6gazelles, and even 1 dinosaur. Eric's niece wants for Eric to randomly pick an animal to ride. What is the probability (expressedas a percent) that Eric picks a horse, a unicorn, or a zebra?b. Eduardo has in his pocket $1 in pennies, $1 in nickels, and $1 in dimes. If he randomly pulls out just one coin, what is theprobability that he will pull out a dime?c. P(rolling an 8) with one regular die if you roll the die just once.d. P(dart hitting a shaded region) if the dart is randomly thrown and hits the target at right.target
