A student must pass through two sets of traffic lights on his way to work. The first light is red 50% of the time, yellow 5% of the time and green 45% of the time. The second light is red 20% of the time, yellow 10% of the time and green 70% of the time. Assuming that the lights operate independently, what is the probability that the student has to stop at least one time on his way to work?...

1 a.) Suppose that only 25% of all drivers come to a complete stop at an intersection having flashing red lights in all directions when no other cars are visible. What is the probability that, of 15 randomly chosen drivers coming to an intersection under these conditions, exactly 3 will come to a complete stop? answer.225 1. b) Now suppose that only 20% of all drivers come to a complete stop at an intersection having flashing red lights in all...

Please answer with method or formula used. A) Puenaa is getting married tomorrow, at an outdoor ceremony in the desert. In recent years, it has rained only 5 days each year. Unfortunately, the weatherman has predicted rain for tomorrow. When it actually rains, the weatherman correctly forecasts rain 90% of the time. When it doesn't rain, he incorrectly forecasts rain 10% of the time. What is the probability that it will rain on the day of Puenaa's wedding? B) A...

An indicator light can be in one of three states: OFF, FLASHING and ON, with probabilities 1/2, 2/5 and 1/10 respectively. A test panel has five such lights whose states are mutually independent. (a) What is the probability that three or more lights are OFF and at most one is ON? (b) A second test panel with five such lights is observed independently. Let X be the total number of lights which are FLASHING among the two panels. Determine the...

In a large university, statistics show that 75% of students live in dormitories. Thus, for any student chosen at random, the university administration estimates a probability of 0.75 that the student will live in dormitories. A random sample of 5 students is selected. Answer the following questions. 1.What is the probability that the sample contains exactly 3 students who live in the dormitories? 2.What is the probability that fewer than 2 students live in the dormitories? 3.What is the expected...

Consider randomly selecting a student at a large university, and let A be the event that the selected student has a Visa card and B be the analogous event for MasterCard. Suppose that P(A) = 0.7 and P(B) = 0.4.(a) Could it be the case that P(A ∩ B) = 0.5? Why or why not? [Hint: For any two sets A and B if A is a subset of B then P(A) ≤ P(B).] C) What is the probability that...

1. In light of the COVID-19 situation in the US, the chance any one of the 27 Jesuit Consortium Colleges opening for fall 2020 semester with on-site student presence on campus is 15%. Father Luige Mario, who is in charge of campus readiness this year, is trying to determine how many campuses, if any, will be ready. What distribution will Father Mario use to determine how many Colleges will need to be ready by fall 2020? What is Father Mario’s...
