The probability of spinner pointer landing on blue color region is equal to 1/3 .
As given in the question,
Total colors in the spinner is equal to 6
Each color is 2 times
Total number of colored region =6
Number of blue region = 2
Probability of pointer landing on blue color region denoted by P(B)
Probability is
= ( Total number of favourable outcomes) / (Total number of outcomes )
⇒ P(B) = 2 / 6
⇒ P(B) = 1 /3
Therefore, the probability of spinner pointer landing on blue color region is equal to 1/3.
