$64 jacket with a 20% discount:

First, we need to change the percentage into a number that we can calculate with. Take the percentage (20%) and divide it by 100(%), since the denominator should always be 100 when changing a percentage into a decimal.
$\frac{20}{100} = 0.20$

Now that we have a number we can calculate with, we need to know how much money we are going to save from the discount. Take the new decimal we just got, and multiply it by the cost of the jacket, which is $64.
$0.20$ × $64 = 12.80$

Knowing that we can save $12.40 on the jacket, we can now subtract the price of the jacket from the discount we get on it.
$64 - 12.80 = 51.20$

You will pay a total of $51.20 on the jacket with the discount added.

WITCHER [35]

Answer:

$P(B' \cup A') = P((A \cap B)') = 1-P(A \cap B)= 1-0.32=0.68$

See explanation below.

Step-by-step explanation:

For this case we define first some notation:

A= A new training program will increase customer satisfaction ratings

B= The training program can be kept within the original budget allocation

And for these two events we have defined the following probabilities

$P(A) = 0.8, P(B) = 0.2$

We are assuming that the two events are independent so then we have the following propert:

$P(A \cap B ) = P(A) * P(B)$

And we want to find the probability that the cost of the training program is not kept within budget or the training program will not increase the customer ratings so then if we use symbols we want to find:

$P(B' \cup A')$
