Answer :
[tex]\text{Probability}=\frac{Number\text{ of favourable outcomes}}{Total\text{ number of outcomes}}[/tex]
Let's get the total number of the items=1+3+4+3+2+3=16items
Let us get the probability of items wit
Step 1
No of items with white or red colour = 4 = No of required items
Step 2'
Find the probability of choosing items with red or white colour
[tex]\frac{4}{16}=\frac{1}{4}[/tex]
