Joe flips the disc shown below 15 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 16th flip will result in the disc landing white side up? (5 points)
fraction 1 over 15
fraction 1 over 2
fraction 1 over 16
fraction 15 over 16
1 over 2
Since the disc has two sides (shaded in darker gray and white), with each side being equally likely to land face up, the probability of the disc landing white side up on the 16th flip is 1/2.
