1 MATH.1 Probability Study Guide Exam not valid for Paper Pencil Test Sessions [Exam ID:14919T 1 Johnny is doing a science experiment. During his experiment, Johnny flips a coin and records the temperature outside. How would you describe these two events? A Inverse events Dependent events Independent events D Direct events 2 Directions: lick and drag each scenario to the correct box. The chart below lists various types of events. omplete the chart below. 8 AM: ob gets the box of cereal off the shelf. 9 AM: Susie finds the box of cereal but does not put it back on the shelf. 8 AM: ob opens the box of cereal but is distracted and leaves the box of cereal on the counter. 9 AM: Susie finds the box of cereal and pours 8 herself AM: ob a bowl. pours himself a bowl of cereal and puts the box back on the shelf. 9 AM: Susie opens the box and pours herself a bowl of cereal.

The amount of each color of marble in the jar is listed below. red 9 yellow 4 blue 2 green Two are selected from the jar. Randomly selecting the second marble is a dependent event if the first marble is not replaced back into the jar before the second marble is selected. an independent event if the first marble is not replaced back into the jar before the second marble is selected. a dependent event if the first marble is replaced back into the jar before the second marble is selected. an independent event if the first marble is replaced back into the jar before the second marble is selected. 4 Henry has 5 pink highlighters and 4 yellow highlighters in his desk. He randomly selects one highlighter and gives it to his neighbor to use. Henry then selects a second highlighter to use himself. How can these two events best be described? A Dependent events Direct events Independent events D Inverse events
3 5 Which statement best describes the events in Group 2? A Simple events Simultaneous events Dependent events D Independent events A bag contains 5 red and 3 blue. A marble is selected at random and replaced back into the bag. Another marble is then selected from the bag. How would you describe these two events? A Independent events Dependent events Inverse events D Direct events 7 When one event is NOT influenced by the outcome of a second event, these events are considered A dependent independent simultaneous D single 8 Each person at a party receives two chances to pick a gift from a secret bag. It is known that there are 5 gifts of money, 10 gifts of jewelry, and 15 gift certificates. Which two dependent events has the greatest probability of happening? A P(money, jewelry) P(jewelry, jewelry) P(money, money) D P(jewelry, gift certificate)
4 9 A bucket contains 8 red pins, 4 green pins, and 7 blue pins. What is the probability of picking a red pin and then a blue pin with replacement? 15 A D A bag contains 5 yellow, 3 red and 7 blue. What is the probability of randomly selecting two red without replacement? A D A number cube containing the numbers 1 through is rolled two times. What is the probability of rolling two odd numbers? A D 3
5 12 Greta has a bag that contains the following: 5 red 3 yellow 4 blue 2 green purple If two are picked from the bag without replacement, which situation has the 3 probability of? 190 A 2 red 2 yellow 2 blue D 2 green E 2 purple 13 Directions: lick on a box to choose each answer you want to select. You must select all correct answers. Several names of students are placed in a hat. The probability of drawing a girl's name is. If two names are selected with no replacement, identify each set of 13 events that have equivalent probabilities. The probability of choosing a boy's name and then a girl's name The probability of choosing a girl's name and then a boy's name The probability of choosing a boy's name and then another boy's name The probability of choosing a girl's name and then another girl's name
6 14 Given the cards shown, the situation that has the highest probability is choosing a A two and then a three without replacement two and then a five without replacement five and then a two with replacement D three and then a two with replacement 15 A bag contains 5 yellow, 3 red and 7 blue. What is the probability of randomly selecting a yellow marble and a blue marble with replacement? A D 225
