Answer:

0.25

Step-by-step explanation:

Well assuming the result of the spin is uniformely random, the yellow area will come up 1/2 of the time (because it takes up 1/2 of the figure).

If it needs to land on yellow both times in two spins, we can take it step by step.

The probability it lands on yellow after the first spin is 0.5

The probability it lands on yellow and then lands on yellow again is 0.5 * 0.5 = 0.25

Think of both spins as 50% yellow, 50% non-yellow

We have 4 options

yellow, yellow

yellow, non-yellow

non-yellow, yellow

non-yellow, non-yellow

Each option is equally probable, so the probability of "yellow, yellow" is 0.25
