Question

Shelley just returned from a spring break volunteer trip. She is shopping for a photo album that will showcase her photos from the trip. The albums range in photo capacity and orientation. Horizontally Vertically 2 4 50 photos 100 photos 6 2. What is the probability that a randomly selected photo album holds exactly 50 photos given that the photo album is oriented horizontally?

Answer 1

Let the probability of an album holding 50 photos be Pr(A).

And the probability of an album holding 100 photos be Pr(B)

Total Horizontal photos = 2 + 6 = 8

Total Vertical photos =4 + 2 = 6

Pr(A) =

The probability of selecting an album that holds exactly 50 photos given that it is horizontally oriented is:

Pr(A/ Horizontal ) =
