The cards are placed face down and mixed up. What is the probability that a randomly selected card has a consonant? Feb 1912:35 PM A red number cube and a blue number cube are rolled. If all numbers are equally likely, what is the probability of the event? The sum is 6 The difference is 6. Two number cubes are rolled. What is the probability that the difference between the two numbers is 4? (different The red cube is greater. cubes) Feb 1912:35 PM Feb 1912:35 PM Feb 1912:35 PM Feb 2410:28 AM complement 2 7.2 Experimental and Theoretical Probability.notebook There are 25 students in study hall. The table shows the number of students who are studying a foreign language. What is the probability that a randomly selected student is not studying a foreign language? Feb 1912:35 PM Each student receives a 5digit locker combination. What is the probability of receiving a combination with all odd digits? February 28, 2014 Two integers from 1 to 10 are randomly selected. The same number may be chosen twice. What is the probability that both numbers are less than 9? Feb 1912:50 PM Geometric probability A DJ randomly selects 2 of 8 ads to play before her show. Two of the ads are by a local retailer. What is the probability that she will play both of the retailer’s ads before her show? Feb 1912:50 PM A figure is created placing a rectangle inside a triangle inside a square as shown. If a point inside the figure is chosen at random, what is the probability that the point is inside the shaded region?
