Answer:
9/64
Step-by-step explanation:
Given,
White balls = 5
Black Balls = 3
Total Balls = 5 + 3 = 8 balls
P (1st black ball) = 3/8
If there is replacement, P (2nd black ball) = 3/8
P (Both balls are black)
= P (1st black ball) x P(2nd black ball)
= 3/8 x 3/8
= 9/64

Answer:
B = 900 Libros
A = 2700 Libros
C = 1800 Libros
Step-by-step explanation:
A = 3B
2B = C
A + B + C = 5400
3B + B + 2B = 5400
6B = 5400
B = 5400 / 6
B = 900 Libros
A = 3B
A = 3(900)
A = 2700 Libros
C = 2B
C = 2(900)
C = 1800 Libros
