Answer:
Step-by-step explanation:
<span>W = event where white marble is drawn
B = event where black marble is drawn
The two events W and B are independent. This is because the marble taken out on the first draw is put back into the bag. Since W and B are independent, we can use this rule
P(W and B) = P(w)*P(B)
Use the rule to get
P(W and B) = P(W)*P(B)
P(W and B) = (1/2)*(1/4)
P(W and B) = (1*1)/(2*4)
P(W and B) = 1/8
1/8 is equivalent to 0.125. Use long division or a calculator
0.125 = 12.5% </span>
Answer:
C) 846 in^2
Step-by-step explanation:
(15x48) + (21x3x2) = 846
Answer:
x + y = 5
3x + 3y = 15
Step-by-step explanation:
let x represent apple and y represent orange
Hence x + y = 5
and 3x + 3y = 15
Solving both equations simutaneously
From first equation, x = 5-y
Substitute x=5-y into the second equation
3(5-y)+3y = 15
y= 0
x = 5-0 = 5
