b. Suppose you have one pair of jeans of each possible style and color in the table. What is the probability of choosing a pair of black jeans at random?

Style Color

Answer 1

A. for each style there are 5 colors so 4*5 = # of choices ,


B. How many black pairs of jeans can there be , divide that by answer to A .

Answer 2

okay well ive been trying to figure this out and i thought it was 4 pairs 1/5 so is it .... 20 pairs 1/5?

Answer 3

Yes, it is. :)

Answer 4

Find the sample space for tossing 2 coins. Then find P(exactly 1 head). can you help with this

Answer 5

I think I can, first we have to figure out all the possibilities
TT
TH
HH
HT (I'm 80% sure this one still counts)

Then how many of them have one Heads or "H", and divide that by how many possibilities

1.No
2.Yes
3.No
4.Yes

2/4 = 1/2

Answer 6

Really? I thought it was that but I second guessed myself and said 1/8

Answer 7

Yep, there is only 2^c possibilities.
