Question

Jacob flips the disc shown below 14 times: A disc with two layers is shown. The top layer is shaded in a darker shade of gray, and the lower section of the disc is white. What is the probability that the 15th flip will result in the disc landing on white? (1 over 15) (14 over 15) (1 over 2) (1 over 8)

Answer 1

Hope this helps but I think the answer is the third option (1/2).

Answer 2

The chances are unrelated, so the 15th flip is not influenced by the others. The chance will be 1 over 2, ie., 50%.
