Answer:
5/8
Step-by-step explanation:
Find P(x = 3 blues for the 2 draws)
two draws
Binomial probability.
we know p = 3/8 for blue, else q = 1 - q = 1 - (3/8)
X = # of blue marbles left in the bag.
apparently it looks like there are 8 marbles in the bag, 3 are blue, 5 are red
X = 3 , means the draw was a red 5/8 for the first draw
the 2nd draw can be a blue or a red so, probability is 1
P(X = 3) = (5/8) * 1 = 5/8
Put 4:3 into a fraction like 4/3 and make it equal to the number of boys
4/3=216/x
(find x by cross multiplying)
x=162 girls

hope this helps!!! :)
2 times 18 equals 36... Did I do a good job answering your question?? If so, brainliest, please. :)
The equation for the length is L=2W - 3. The perimeter is 48 cm and the equation for finding the perimeter is P = 2W + 2L. Substitute the formula of L into the formula for perimeter and solve algebraically:
The correct answer is A) length = 15cm; width = 9cm
