Gennadij [26K]

Answer:

D. Both B and C

Step-by-step explanation:

The government will give the same amount of available social security number to each state. So the available social security number pool will be divided by the total number of states. There are a total of 50 states in the USA. If the number pool is 5 x 10^9, then each state going to have:

5 x 10^9 /50= 0.1 * 10^9 = 1*10^8

The answer will be D since 1 x 10^8 and 100,000,000 is the same number

If the probability of a student taking a calculus class is 0.10, the probability of taking a statistics class is 0.90, and the p
Stells [14]

Answer:

93% probability of a student taking a calculus class or a statistics class

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a student takes a calculus class.

B is the probability that a student takes a statistics class.

We have that:

A = a + (A \cap B)

In which a is the probability that a student takes calculus but not statistics and A \cap B is the probability that a student takes both these classes.

By the same logic, we have that:

B = b + (A \cap B)

The probability of taking a calculus class and a statistics class is 0.07

This means that A \cap B = 0.07

The probability of taking a statistics class is 0.90

This means that B = 0.9. So

B = b + (A \cap B)

0.9 = b + 0.07

b = 0.83

The probability of a student taking a calculus class is 0.10

This means that A = 0.1

A = a + (A \cap B)

0.1 = a + 0.07

a = 0.03

What is the probability of a student taking a calculus class or a statistics class

A \cup B = a + b + A \cap B = 0.03 + 0.83 + 0.07 = 0.93

93% probability of a student taking a calculus class or a statistics class
