A bag contains 4 Blue balls, 7 Red balls, and 8 Green balls. Two balls are going to be drawn from the bag (one at a time) and then put to the side (they are not returned to the bag). Let event B = blue ball chosen, R = Red ball chosen, and G- Green ball chosen. What is P(BR)? Write an answer to 4 decimal places.
Consider the following statement: The probability that Mary (spends at least, spends at most, spends less than, spends more than) 20 minutes per day exercising. Depending on which phrase you chose in parenthesis you end up with a different expression and meaning in terms of probability theory. For instance, P ( x ≤ 20 )(probability Mary spends at most 20 minutes exercising) means something different from P ( x > 20 )(probability Mary spends more than 20 minutes exercising). Write an expression related to your major for each of phrases above and label them with the correct mathematical symbol (use my example as a reference, but I encourage creativity here!). Then explain the differences between the four statements i.e., differences between at least, at most, less than, more than.
A commuter must pass through three traffic lights on her way to work. For each traffic light, the probability that it is green when she arrives is 0.6. The lights are independent. 3 (a) Compute the probability that all three lights are green. (b) The commuter goes to work five days per week. Let X be the number of times out of the five days in a given week that all three lights are green. Assume the days are independent of one another. Determine the distribution of X. (c) Calculate P(X= 3).
Q2: Two numbers x and y are selected at random between zero and one. Let the events A, B, and C be defined as follows: A = (x > 0.6), B = (y > 0.2), and C = (x > 2y). Are the events A and B independent? Are A and C independent?
A bag contains 9 Blue balls, 5 Red balls, and 7 Green balls. Two balls are going to be drawn from the bag (one at a time) and then put to the side (they are not returned to the bag). Let event B = blue ball chosen, R = Red ball chosen, and G = Green ball chosen. What is P(BR)? Write an answer to 4 decimal places. Ih
By rewriting the formula for the multiplication rule, you can write a formula for finding conditional probabilities. The conditional probability of event B occurring, given that event A has occurred, is P(B A)=P(A and B)P(A). Use the information below to find the probability that a flight departed on time given that it arrives on time. The probability that an airplane flight departs on time is 0.89. The probability that a flight arrives on time is 0.89. The probability that a flight departs and arrives on time is 0.82. The probability that a flight departed on time given that it arrives on time is ____ (Round to the nearest thousandth as needed.)
By rewnting the formula for the multiplication rule, you can write a formula for finding P(A and B) P(A) conditional probabilities.
