Joel and Maja have studied for an exam that they will write for overgrading. The probability distribution for the grades (3, 4 or 5) are given below. If Joel writes the exam first and announces to Maja that he got a 5, then what is the probability that Maja only gets a 3? J/M 3 4 5 3 0.21 0.11 0.04 4 0.02 0.32 0.13 5 0.01 0.03 0.13
The weights of steers in a herd are distributed normally. The variance is 10,000 and the mean steer weight is 1100⁢lbs. Find the probability that the weight of a randomly selected steer is between 919 and 1180⁢lbs. Round your answer to four decimal places.
The life of light bulbs is distributed normally. The variance of the lifetime is 900 and the mean lifetime of a bulb is 550 hours. Find the probability of a bulb lasting for at least 583 hours. Round your answer to four decimal places
Assume that you have a random variable X which is binomially distributed, and someone told you that the mean of this variable is (6) and variance is (4.2). Find P(X=5).
Consider X is a random variable and has equal probability of being -1,0,+1. What is the correlation between X and Y while Y=X*X.
When X is a binomial random variable, the mean of the probability distribution = np. A jury has 12 people on the jury. If a certain town has a population that is 9 percent a certain race, how many people of that race would you expect would be on the jury if jury selection was random (and every person was equally likely to be on the jury). Round answers to 4 decimal places as needed.

Aurah wanted to know the distribution of the number of students with blood type O. She randomly selected six students and recorded their blood type. Suppose the probability of a student having blood type O is 0.45 and X be the number of students with blood type O. Which of the following is(are) TRUE about the experiment? A. It is a Bernoulli experiment with probability of success equal to 0.45B. The success in this experiment is observing six students with blood type O.C. X-Bin(6.0.45)D. A single trial of the experiment corresponds to six students.
