At a college the scores on the chemistry final exam are approximately normally distributed, with a mean of 75 and a standard dev
AysviL [449]

Answer:

b) Chemistry

Step-by-step explanation:

To compare both scored we need to standardize the scores using the following equation:

\frac{x-m}{s}

Where x is the score, m is the mean and s is the standard deviation. So, 82 on chemistry is equivalent to:

\frac{82-75}{15}=0.4667

Because the mean of the scores on the chemistry final exam is equal to 75 and the standard deviation is 15

At the same way, 80 on Calculus is equivalent to:

\frac{80-83}{13} =-0.2308

Because the mean of the scores on the calculus final exam is equal to 83 and the standard deviation is 13

Now, we can compare the values. So, taking into account that -0.2308 is lower than 0.4667, we can said that the student do better in Chemistry.

3/5 x 2/4 = 0.3

2/5 x 3/4 = 0.3

Therefore, the probability that he chooses trees of two different types is 30%.
