Question

Need my answer checked

A box of photographs contains 13 wedding photographs, 4 vacation photographs, and 8 holiday photographs. One photograph is randomly selected.

What is the probability that the photograph is a holiday photograph, given that it is not a wedding photograph?
A.12/25
B.12/13
C.1/2
D.2/3

Answer 1

How many photos in all?

Answer 2

i say that its either A or B because it speaks about wedding photos and holiday and theres 13 wedding photos but all together its 25 @cwrw238

Answer 3

No....

Answer 4

There are 25 photos in all, but it says "given that it is not a wedding photograph". So it will not be a wedding photo, so we can subtract 25 - 13.

Answer 5

What does that get you?

Answer 6

12

Answer 7

Yes.

Answer 8

So there will be 12 cards that can be chosen from.

Answer 9

And how many holiday photos?

Answer 10

this is similar to the card question

Answer 11

Ikr -.-

Answer 12

8

Answer 13

Gotta learn. Can't keep asking same questions...

Answer 14

Yes, 8, so the probability is 8/12.

Answer 15

Now we have to do a little simplifying...

Answer 16

Divide both numbers by 4...

Answer 17

\(\dfrac{8 \div 4}{12 \div 4}\)

Answer 18

2/3

Answer 19

Yes!

Answer 20
