k0ka [10]

The number of T-shirt bought by Shilpa from a clothing store = 30
Percentage of T-shirt that were blue = 20%
Then Number of T-shirt that were blue in color = (20/100) * 30
   = 2 * 3
   = 6
Number of T-shirts that were black in color = (1/2) * 30
   = 15
Then
The total number of T-shirts that were black and blue = (15 + 6)
   = 21
Then
The total number of T-shirts that were neither black nor blue = 30 - 21
   = 9
So the number of T-shirts that were neither black nor blue was 9.

Phoenix [80]

We are given that:

The number of yellow marbles = 3

Number of red marbles = 9

Number of Blue marbles = 8

Total marbles = 3 + 9 + 8

Total marbles = 20

Now, we have to calculate the probability of obtaining two blue marbles without replacement.
