lightb nt types.The lifetime of the first lightbulb (in years) is described by an exponential random variable X with mean 1, and the second lightbulb's lifetime is described by an exponential random variable Y with mean 2, independent from X. Let T be the amount of time from now until either one of the lightbulbs burns out, so T min(X,Y).

Use the basic probability principle to solve the following problem. Express each probability as a fraction reduced to lowest terms. A 12-sided die is rolled. The set of equally-likely outcomes is (1,2,3,4,5,6,7,8,9,10,11,12}. Find the probability of rolling a 6. The probability of rolling a 6 is (Type an integer or a simplified fraction.)

The below was the answer I received when I asked the following question. Dr. Deming’s Red Bead Experiment is an exercise in the laws of probability. The workers were frustrated because no matter what they did, the outcome was not predictable. If the paddle holds 50 beads and there are 500 white beads and 50 red beads in the box, what is the probability, using one sample, of filling a paddle with 47 white beads and only three red beads? What I need to understand is how did you get the highlighed answers below because these require a factorial of 500 and I have not found anything that will calculate that. Thank you Step 1 Given Information: Number of white beads = 500 Number of red beads = 50 Total number of beads = 550 Step 2 The probability, using one sample, of filling a paddle with 47 white beads and only three red beads can be determined as follows: Probability = C47500*C350C50550=(2.94*10^66) (19600)(3.44*10^71)=0.1675
Hello! I need help with following probability problem. Thank you in advance..!
A new boarding policy has been proposed by an airline. Frequent flyers and non-frequent flyers were asked for their opinions, and the results are summarized in the table shown here. Find the probability a person chosen at random from among the people surveyed favors the new policy and is a frequent flyer. Enter your answer correctly to two decimal places. Remember, a probability is expressed as a number between zero and one, inclusive. Opinion on Policy In Favor Of (A) Neutral (B) Opposed To (C) Frequent Fliers (D) 48% 23% 4% 75% Non-Frequent Fliers (E) 15% 3% 7% 25% 63% 26% 11% 100%
