Answer:
The probability mass function of random variable X which represents the number of blue marbles drawn in 2 draws with replacement.
X | P(X)
0 | 0.390625
1 | 0.46875
2 | 0.140625
The probability of drawing exactly one blue marble = 0.46875
0.46875 as a simplified fraction is ------ 15/32

Answer:
21.46 mm^2
Step-by-step explanation:
The area of the square is ...
A = s^2 = (10 mm)^2 = 100 mm^2
The area of the circle is ...
A = πr^2 = π(5 mm)^2 = 25π mm^2 ≈ 78.54 mm^2
Then the shaded area is ...
100 mm^2 -78.54 mm^2 = 21.46 mm^2 . . . shaded area
Answer:
Because the side w is 
the side opposite the right angle (the hypotenuse) + 
(because of the 30-60-90 triangle), we just need to divide by the hypotenuse by 2 and then add three. Knowing this, our answer will come out to be 2 + .
