Answer:
Probability of no one picking up a defective product = 571 / 1540
Step-by-step explanation:
Total number of items = 22
non-defective items = 22-3 = 19
Probability of all three picking up non-defective products
= 19/22 * 18/21 * 17/20
= 969/1540
Probability of at least one picking up a defective product
= 1 - 969/1540
= 571/1540
(=0.371, approx.)
Answer: 137.17 miles
Step-by-step explanation: To know the driven miles, we will have to find the extra money paid divided by the unitary price of each driven mile.
Extra money=$29.46-$25=$4.46
Miles=
=31.17 miles
However, this price per mile is only charged after 100 miles, therefore we will have to sum the extra miles driven and the 100 miles for the basis
Total=100 miles+31.17 miles=137.17
