What is Normal Distribution?
Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Given that, Mrs. smith reading class can read a mean of 175 words per minute with a standard deviation of 20 words per minute. The top 3% of the class is to receive a special award. we need to find the minimum number of words per minute a student would have to read in order to get the award.
The z-value separating the top 3% of a normal population from
the bottom 97%.
That value is z = 1.8808
The associated raw score value using x = zs + u
x = 1.8808*20 + 175
x = 212.62
213 is the minimum number of words per minute.
Hence 213 is the minimum number of words per minute a student would need to read in order to get the award.

Answer:
All the 36 outcomes are equally likely.
Step-by-step explanation:
The sample space of rolling a single six-sided dice is:
S = {1, 2, 3, 4, 5, 6}
Then the sample space of rolling a pair of six-sided dice is:
S₁ = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)
(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)
(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)
(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)
(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)
(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}
All the 36 outcomes are equally likely, i.e. all the outcomes has the same probability of success, .
