Step 1 :Given that the wheel has 10 slices in total, and 2 of them are white.
Step 2 :If the arrow stops on a white slice, Dan wins a gift card.
Step 3 :So, the odds of Dan winning a gift card is the number of white slices divided by the total number of slices.
Step 4 :Using the formula for odds, \(\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\), we substitute the given values.
Step 5 :Substituting the given values, we get \(\frac{2}{10} = 0.2\).
Step 6 :Final Answer: The odds of Dan winning a gift card is \(\boxed{0.2}\) or 20%.
