you randomly select a month of the year. What is the probability that you select a month with 28 or 30 days in it?

OpenStudy (anonymous):

how many months have 30 days?

OpenStudy (anonymous):

And how many have 28?

OpenStudy (anonymous):

First you figure out how many months have 28 or 30 days, once you have that divide it by 12 and that is your answer

OpenStudy (anonymous):

28 =1?

OpenStudy (anonymous):

February has 28, now which months have 30?

OpenStudy (anonymous):

thirty days hacienda, April, June, and sombrero.

OpenStudy (anonymous):

mmm 8 months have 30?

OpenStudy (anonymous):

April, June, September, and november

OpenStudy (anonymous):

Plus February equals what?

OpenStudy (anonymous):

so do i add the months? O.o

OpenStudy (anonymous):

5?

OpenStudy (anonymous):

Yes and divide by 12 that's your answer 5/12

OpenStudy (anonymous):

so the answer is 5/12?

OpenStudy (anonymous):

ohhhhhhhhhhhhh! i kinda get it lol

OpenStudy (anonymous):

Yep, you have a 5/12 chance of picking one with 28 or 30 days

OpenStudy (anonymous):

Because the top number is equal to what they are asking(so in this problem the months with 28 or 30 and the bottom is all of what you are choosing from(in this problem the all the months, so 12) so you get 5/12
