Answer:
a)
b) 80.42%
c) 87.24%
Step-by-step explanation:
a)
Since the probability of taking a color does not depend on the previous color obtained, the events are independent, so the probability of getting exactly two of each color is
b)
We can model this with a binomial distribution treating an orange candy as a “success” and any other color as a “failure”.
So the probability of “success” p equals 0.20 and the probability of “failure” q equals 0.80 and the probability that there are at most 5 orange candies out of 20 equals
this can be computed either by hand or with the aid of a computer to obtain that probability that there are at most five orange candies is 0.8042 0r 80.42%
c)
In this case we use once more the binomial distribution but this time “success” is getting blue, green or orange that has a probability of 0.24 + 0.16 + 0.20 = 0.60 and “failure” has a probability of 0.4.
Now we are looking for
again by hand or with the computer help, this probability equals 0.8724 0r 87.24%
Answer:
√37
Step-by-step explanation:
An irrational number is a number that never terminates nor repeats.
Let's go through each of the answer choices.
1) √100 is just 10. This is not irrational.
2) √81 is just 9. This is again not irrational.
3) √64 is 8. Not irrational.
4) √49 is 7. Again, not irrational.
5) √37 is 6.08276253... This number will never end and it doesn't repeat. Therefore, √37 is irrational.
And this is our answer.
And we're done!
