The normal distribution is also known as the Gaussian distribution. The correct option is B, while the approx z-score is 0.31.
<h3>What is Normal Distribution?</h3>
The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Since the normal distribution is symmetrical about the mean. Therefore, the correct option is B, while the approx z-score is 0.31.

(15*36)/100+15
Okay, so if there’s a can that holds 16 cups, and she only fills it halfway, there are 8 cups to water the plants with.
8/15= 0.53 Cups Per Plant.
The best investment of the company is in southeast contract. The probability of profit of this contract is maximum 50% and of loss is minimum 20%.
<h3>What is probability?</h3>
Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
A company has an opportunity to bid on three contracts. Probability of profit and loss by all three contract is listed in the table below.
Contract profit, (P)* of profit, (P)* to break even loss, (P)* of loss
- Southeast $45,000, 50% 30% $6,000, 20%
- Southwest $60,000, 35% 40% $10,000, 25%
- California $112,000, 20% 40% $40,000, 40%
The company which will give the maximum profit probability and minimum loss probability will be the best investment.
In the above table, the southeast contract has the maximum probability of profit, which is 50% among all the contracts. Similarly, it has the lowest probability of loss, which is 20%.
Thus, the best investment of the company is in southeast contract. The probability of profit of this contract is maximum 50% and of loss is minimum 20%.
