Using the probability concept, considering complementary probabilities, there is a 0.12 = 12% probability that the integer is of 20 or more.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
If two events are complementary, the <u>sum of their probabilities is of 1</u>. In this problem, we have that an integer being less than 20 is complementary to an integer being 20 or more.
We have that:
- There is a 0.88 probability that the number is less than 20.
- There is a x probability that the number is 20 or more.
These events are complementary, hence:
0.88 + x = 1
x = 1 - 0.88
x = 0.12
There is a 0.12 = 12% probability that the integer is of 20 or more.

The answer would be 15. The average of 6, 7, 8, 9, and 15 is 9. Hope this helps.

Step-by-step explanation:
25/100 x 79
= 19.75
= 79 - 19.75
= $59.25 (before tax)
7/100 x 59.25
= 414.75/100
= 4.15
= 59.25 + 4.15
= $63.4 (after adding tax)
First we have to take out the percentage of discount and minus it from the total cost . To find the discounted price with tax, we have to take out the percentage of the tax from the discounted amount and add it to the discounted amount to get the total cost.
