You are interested in the number of people that will visit your restaurant in the noon hour. Historically, there is a 10% chance that more than 10 customers will visit, a 30% chance that more than 8 customers will visit, a 50% chance that more than 6 customers will visit, a 80% chance that more than 4 customers will visit, and a 95% chance that at least 2 customers will visit during the noon hour. What is the probability that 4 or less customers will visit the restaurant -- the number required to break even financially for the day? Express your answer as a percent value. So if your answer is 100% for example, enter 100. Round your answer to the nearest percent.

You enrolled in a biology class and don’t know yet which Biology Professor and Biology Laboratory Assistant you will get. You like Professor Smith (Biology Professor), but the professor will be randomly selected from a group of 10 professors. You also like Ms. Jones, who is one of 5 Biology Laboratory Assistants. Laboratory Assistants are also randomly selected for classes. The probability of getting both Professor Smith and Ms. Jones for the same biology class = 1/50. What is the probability that you will get at least one of your instructor preferences (Professor Smith or Ms. Jones)?
In a classroom of 27 students, there are 17 girls and 10 males. Mr. Stover wants to randomly select a student but states that the probability of selecting a female student is a lot larger than selecting a male student. Is this assumption correct? Explain your answer.
Pedro has just entered university and has been informed that there is a 30% chance of receiving a scholarship.

Tell Peter what the probability is that he will graduate.
The final match of world championship soccer is to be played between England and the Netherlands. The star player for the Dutch team, Dennis Nightmare, has been injured. The probability of his being fit enough to play in the final is being estimated at 75%. Pre-game predictions have estimated that, without Nightmare, the probability of a Dutch win is 30% and with Nightmare, 50%. Later, you hear that the Dutch team has won the match. Without having any other information about the events that occurred, what would you say was the probability that Dennis Nightmare played in the final?

Every summer, Madison goes on a week- long canoe trip with her childhood camp friends. After the trip, she usually purchases some oars from the destination city. Her collection of oars is organised by year and type of wood. The probability that an oar was purchased in 2013 is 0.4, the probability that it was made from spruce wood is 0.4 and the probability that it was purchased in 2013 and was made from spruce wood is 0.1. What is the probability that a randomly chosen oar was purchased in 2013 or was made from spruce wood?
