Answer:
133/152
Step-by-step explanation:
The probability of 2 independent events is the product of the individual events. Independent means the first event has no effect on the probability of the second event. Since we are replacing the first marble, the first even has no effect on the probability of the second event.
There are 48 total marbles
Let A = pulling a blue marble
Let B = pulling a red marble
So
P(A) = 14/48
P(B) = 19/48
and
P(A then B) = (14/48)(19/48) = 266/2,304 = 133/1,152

Answer: The results do not represent the population because the sample does not represent professors from different areas.
Step-by-step explanation:
Since Traverion wants to find the answer to the question “How much money does the average college professor make?”
He only surveys 50 professors from the university in his hometown.
Although he should survey professors from different areas but he only perform his survey only a specific university in his hometown.
Therefore, the survey is biased as the sample size is too small.
Hence, The results do not represent the population because the sample does not represent professors from different areas.
