Suppose your waiting time for a bus in the morning is uniformly distributed on (0,5), whereas waiting time in the evening is uniformly distributed on [0,10] independent of morning waiting time. Hint: Uniform distribution with range (A, B) has mean and variance respectively. u = 478; o2 = (B-4)2 12 a. If you take the bus each morning and evening for a week (i. e., 5 days), what is your total expected waiting time? [Hint: Define random variables X1, .. X10 and use a rule of expected value.) b. What is the variance of your total waiting time? Hint: compute the variances of Uniform(0,5) and Uniform(0,10). c. What are the expected value and variance of the difference between morning and evening waiting times on a given day? d. What are the expected value and variance of the difference between total morning waiting time and total evening waiting time for a particular week?

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

answer: 1 + 1 = 11

the correct answer is the last option

okay, what do you want us to do?

anyway, the cost of labor per hour for repair shop b is $50 per hour.

the repair bill for your car at repair shop b is $553

the parts for repair shop b cost is   $497.07
