Given :

Number of red shirts = 3

Number of blue shirts = 4

Number of black shirts = 1

Number of grey shirts = 2

So, total outcomes = 3 +4 + 1 + 2

= 10

Favorable outcomes (non blue shirts ) = 3 + 1 + 2= 6

We know, probability = favorable outcome/Total outcome 

= 6/10

= 3/5 or 0.60

 

Thus, probability of picking non blue shirt is 3/5 or 0.60
