A data scientist studying a manufacturing process classifies each item produced by the process as either Poor, Acceptable, or Ex
Genrish500 [490]

Answer:

0.214 ; 0.064 ; 0.3859 ; 0.9966 ; 0.135

Step-by-step explanation:

Given the distribution :

Poor ___ Acceptable ____ Excellent

0.25 _____ 0.6 _________ 0.15

The data scientist receives three items produced by the manufacturing process.

Find the chance that:

a. all of items are Acceptable

0.6 * 0.6 * 0.6 = 0.6^3 = 0.214

b. none of the items is Acceptable

P(not acceptable) = 1 - p(acceptable) = 1 - 0.6 = 0.4

0.4 * 0.4 * 0.4 = 0.4^3 = 0.064

c. at least one of the items is Excellent

P(atleast one) = 1 - P(none)

P(not excellent) = 1 - 0.15 = 0.85

P(none is excellent) = 0.85^3 = 0.614125

Hence,

P(atleast one is excellent) = 1 - 0.614125 = 0.3859

d. not all of the items are Excellent

P(not all) = 1 - p(All)

P(all excellent) = 0.15^3 = 0.003375

P(not all are excellent) = 1 - 0.003375 = 0.9966

e. there is one item of each class:

P(poor) * p(acceptable) * p(excellent) * (number of classes)!

0.25 * 0.6 * 0.15 * 3!

= 0.135

6) John purchased 120 shares of Walmart stock at $58.02 each. He sold the stock for $120.98.
antiseptic1488 [7]

Answer:

John lost $6841.42.

Step-by-step explanation:

Let's find out how much John paid for the stock he bought.  Each share cost $58.02. He bought 120 shares.  Multiply the price by the number of shares.

58.02 x 120 = 6962.40

He sold the stock for $120.98 -- a huge loss!  (We are not told that the $120.98 is the selling price of one share, so I'm assuming that's what John sold all his shares for.)

Find the difference to see what his loss was.

$6962.40 - $120.98 = $6841.42 LOST!
