The numerator represents the chance of landing on the colour, and the denominator represents the number of spots you could land on. You have a 2 out of 7 chance to land on blue because there are 2 blue spots. This means that for every 2 times out of 7 spins you would land on blue.

Help!!!!!!!!!!!!!!! Simplify 4^(-2)
user100 [1]

hello there! Your answer would be 0.0625 or 1/16.

In this question, you are being asked to multiply 4 to the -2nd power. Your answer would be whatever the inverse of 4 to the 2nd power. Well, 4 to the 2nd power is equivalent to 16, or 16/1, so just slip the numerator and denominator values and you get 1/16. (In decimal form it is 0.0625)

I hope this helps and have a great day!
