25%

Step-by-step explanation:

50% chance for spin one to be gray and 50% chance for spin two to be blue. Put them together for that order and you get 25%.

Roberto Lopez · Answer 2

Let's Take 8 sections and in which 6 are grey and 2 are blue.

The probability that the first spin lands on blue = 2/8 = ¼

The probability that the second spin lands on gray = 6/8 = ¾

The probability that the first spin lands on blue and the second spin lands on gray is

(¼) (¾) = 3/16

These events are independent, so you can just multiply the probabilities
