Document Summary
Instructions: do both of parts h and t, and, if you wish, part e. show all your work and simplify answers as much as practicable. Aids: calculator; one 8. 5 11 or a4 aid sheet; standard normal table; 1 brain. [subtotal = 70/100: a fair coin is tossed four times. [5: compute p (a) and p (b). [5: compute p (a|b) and determine whether a and b are independent or not. [5: suppose x is a normally distributed continuous random variable with mean = 5 and standard deviation = 10, compute p (x 0). [5: find the value of c such that p (x > c) 0. 2266. [7: let a be the event that three tosses took place and let b be the event that the. Determine whether the events a and b are independent or not. [8: let x be a continuous random variable with density function f (x) = (cid:26) 3 x4.
