A) 0.9803; 0.4803
B) 32
We calculate the z-score for this problem by using the formula:

Using our formula, we have:

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this score is 0.9803.
To find the probability it is between the mean and this, we subtract the probability associated with the mean (0.5) from this:
0.9803 - 0.5 = 0.4803.
To find B, we first find the z-score for this. Using a z-table (http://www.z-table.com) we see that the closest z-score would be 2.33. We then set up our equation as

Multiplying both sides by 0.85 we have
2.33(0.85) = 0.35√n
1.9805 = 0.35√n
Divide both sides by 0.35:
1.9805/0.35 = √n
Square both sides:
(1.9805/0.35)² = n
32 ≈ n

Answer: To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn't matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.
Answer:
1/52
Step-by-step explanation:
Let's first examine how many 3 of clubs there are in a deck of 52 cards
In a deck of cards there are separated into 4 groups, Spades, Hearts, Diamonds, and Clubs. And from each of those groups they can further be separated from 1 to 13 (11, 12 and 13 are the jack, queen and king respectively)
Therefore, there is only 1 "3 of clubs" in a deck of cards, so the probability of drawing one out is
1/52
