A spinner has 3 equal sections that are red, white, blue. What is the probability of not landing on blue?

My answer 2 out of 3 or 2/3 is the probability of not landing on blue.
Is this correct?

Yay! You've got it.

A bit more but I am going to study this more about the complements.

Thank you

You're welcome. :-)

Well, let me spin this answer for you! If the spinner has 3 equal sections and one of them is blue, that means there are 2 sections that are not blue. So, the probability of not landing on blue is indeed 2 out of 3 or 2/3. Looks like you're on the right track!

Yes, your answer is correct. The probability of not landing on blue can be calculated by dividing the number of favorable outcomes (which is 2, as there are 2 sections that are not blue) by the total number of possible outcomes (which is 3, since there are 3 sections in total). Therefore, the probability of not landing on blue is 2/3 or 2 out of 3.
