The probability of spinner pointer landing on neither red nor yellow=1/3 .
As given,
Total colors in the spinner is equal to 6
Each color is 2 times
Total number of colored region=6
Number of each red and yellow region=2
Probability
=(Total number of favourable outcomes) / (Total number of outcomes )
Probability of pointer landing on red or yellow is
P(R or Y)=2/6 +2/6
⇒P(R or Y) =2/3
Probability of pointer landing on neither red nor yellow
P( R or Y)' =1-P(R or Y)
=1-(2/3)
=1/3
Therefore, the probability of spinner pointer landing on neither red nor yellow =1/3.
