Probability of selecting 2 toys of different types
From the question, we understand that all toys are different i.e. 1 of each type.
And the selection is without replacement;
So, after the first toy is selected; there are n - 1 toys left.
So, the probability is:

Substitute 




Answer:
true~ bc the amount basically
Let the number of shaded square be x. And it is given that total number of squares are 25.

Substituting the values

Performing cross multiplication

So 5 squares should be shaded to create a region with a geometric probability of 0.2 .
The interior angles of a triangle add up to 180 degrees
3x + 2x + x = 180
6x = 180
x = 180/6
x = 30
< C = 2x.......2(30) = 60 <===
< B = 3x.......3(30) = 90
< A = x................. = 30
