Answer 3

P(Red) + P(Blue) + P(Green) = 1

plug in the probability of getting blue and red and solve for probability of getting green

Answer 4

I believe the beginning of the question should read:
"A spinner is divided into sections of \(\color{red}{un}\)equal size, ...."
or else the question is confusing/contradictory.

Answer 7

Mathmate, I agree but maybe the spinner has 100 equal pieces and red has a 25 pieces from it, and blue has 10 pieces, mhmm

@TheSmartOne
I share the same interpretation as yours, except that the OP should understand the duty of verifying the correctness of the question. In this case, the proper interpretation may be obvious because information is fortunately redundant, but in other cases, typos would lead to wild-goose chases.

Wait, I understand what you mean, yes, that is a possible case. In that case, I retract what I said! lol
