Answer: $2.95
Step-by-step explanation:
Given: Probability of losing the $7 =
Probability of winning $14 =
Then, the expected value = (- $7) x ( Probability of losing the $7) + $14 x(Probability of winning $14)
=
=
=
∴ If a doctor pays $7 that the outcome is an odd number, the doctor's
expected value is $2.95.
Answer: divide it by the number of numbers you added up.
Step-by-step explanation:
For example, let's say you had to find the average of 1, 2, and 3. You add all the numbers up to get 6. Since you had to add 3 numbers together (1, 2, 3) to get 6, you divide 6 by 3 to get the mean/average, which in this case, is 2
Answer: Mr. Carlo make the box with the height 4 feet or 5 feet .
Step-by-step explanation:
Since we have given that
Length of a storage box =5 feet
Breadth of a storage box =2 feet
Height of a storage box =h
Volume must be at least 36 cubic feet but no more than 56 cubic feet.
Possibility of h will be 4 and 5
<u>Case I:</u>
<u>Case II :</u>
So, it can be 40 cubic feet or 50 cubic feet .
So, height can be 4 feet or 5 feet .
