Answer:.
Step-by-step explanation:
Follow the formula given below.
P(Mar and Vacation) = P(vacation l march) x P(March)
So it was given above that 5% is the probability that it is March and someone's vacation.
0.05 = P(vacation l march) x ( 1/12)
1 0.05
P(vacation l march)= ------- x --------
12 1
P(vacation l march) = 0.6
So the answer is 60% probability that you will have a vacation given that the month is March.

<h3><u>
Step-by-step explanation:</u></h3>
Each of four friends orders a sweatshirt from a catalog.
There are 15 colors of sweatshirts, 5 of which are all cotton and 10 of which are a blend.
We have to find the probability that the friend order only cotton sweatshirt:
As there are 5 cotton shirts out of which four are to be selected from a total of 15 coloured shirts.
Now we know that a probability is defined as:
Probability=( Number of favourable outcomes)/(Total number of outcomes)/( Total number of outcomes)
So, the probability is:
Hence, the probability is:
