Answer:

a) 83%

b) 0.892

Step-by-step explanation:

percentage that attends class on friday = 74%

percentage that pass because they attend class on friday = 88%

percentage that pass but did not go to school on friday = 20%

a) percentage of students expected to pass the course

  = (74% x 88%) +(88% x 20%)

   = 0.6512 + 0.176

   = 0.8272

   = 83%

b) If a person passes the course, what is the probability that he/she attended classes on Fridays

        = 74% divided by 83%

        = 0.892

creativ13 [48]
Let the price of game, marker, pen and book be $w, x, y and z.

x =  \frac{1}{3} y
y =  \frac{1}{3} z
z =   \frac{1}{3} w
x =  \frac{1}{3} y \\ x =  \frac{1}{3} ( \frac{1}{ 3} z) \\ x =  \frac{1}{3} ( \frac{1}{3} ( \frac{1}{3} w) \\ x =  \frac{1}{27} w
