question is,

If you flip a coin 5 times what is the probability of getting 4 heads, and 1 tails?

total number of outcomes is because you flip a coin there are to possible outcomes 5 times.

Since there is no order it is a combination *this is where I am confused* I thought when you have two different things like,

"how many 4 card hands can be formed with 2 hearts and 2 diamonds" you do 13c2 x 13c2 because you have 13 of each and you are choosing two each.

but what I've seen searching online is when you flip a coin dice 5 times and want 4 heads it's 5c4=5? but what about the tails? shouldn't it be 5c4 x 5c1 because there are 5 heads and 5 tails? Also if this is the same with dice I'd like to know how to do that too.

thanks.
