The perimeter will be
.. P = 2√(16^2 +30^2) = 2*34 = 68
Angie will now have 100 stuffed animals
<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>
32 divided by 2.39 = about 13.3
