Answer:.......
Probability = 
Step-by-step explanation:
Let g represent the number of green beads , and o represent the number of orange beads.
due to the fact that Ann is selecting the bead without replacing i randomly
the probability (Pr) of Ann selecting a green bead and then an orange one =
Answer:
The answer is 2 561,2785 !!!
The answer is 1/4 because all you have to really do is simplify
4(4x + 5)
4(4•7+5)
4(28+5)
4(33)
132
(a) The probability of drawing a blue marble at random from a given box is the number of blue marbles divided by the total number of marbles. We assume that the probability of selecting one of two boxes at random is 1/2 for each box.
... P(blue) = P(blue | box1)·P(box1) + P(blue | box2)·P(box2) = (3/8)·(1/2) + (4/6)·(1/2)
... P(blue) = 25/48 . . . . probability the ball is blue
(b) P(box1 | blue) = P(blue & box1)/P(blue) = (P(blue | box1)·P(box1)/P(blue)
... = ((3/8)·(1/2))/(25/48)
... P(box1 | blue) = 9/25 . . . . probability a blue ball is from box 1
