Smoking and drinking harms the fetus by limiting it's chance of being healthy
Answer:
The binomial distribution, with parameters n = 5 and p = 0.7
Step-by-step explanation:
For each card observed, there are only two possible outcomes. Either it is a name corresponding to a male student, or it is a name corresponding to a female student. Since the cards are replaced, that is, place back in the set, the propability of taking a male student is each obervation is independent from other observations. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
This is done a total of five times.
Which means that
Let X be the number of cards observed in these five trials with a name corresponding to a male student.
Each trial, there is a 7/10 probability of observing a male student. So
So the correct answer is:
The binomial distribution, with parameters n = 5 and p = 0.7
They are not perpendicular.
