(3/7)*(2/7)=(6/49) You have a 6 out of 49 probability.
217/5 = 43.4With 43 boxes, you can take care of 215 balls. After that, you have a decision to make:You have 2 balls left over. You can either slip them into your pocket and walk away, orput them into Box #44.
The probability that all balls are red is 0.50 or 50%.EXPLANATIONSuppose there are 4 boxes with 5 balls each.Box A has 2 red balls.Box B has 3 red balls.Box C has 4 red balls.Box D has 5 red balls.The probability of drawing at random 2 red balls for each box is:Box A; P(2 red balls) = (2/5)∙(1/4) = 2/20 = 1/10Box B; P(2 red balls) = (3/5)∙(2/4) = 6/20 = 3/10Box C; P(2 red balls) = (4/5)∙(3/4) = 12/20 = 6/10Box D; P(2 red balls) = (5/5)∙(4/4) = 20/20 = 10/10Now, suppose we do the drawing of 2 balls experiment 10 times on each boxgiving a total of 40 experiments. The probabilities calculated above are the"expected" results, that is; out of the 40 experiments (drawing of 2 balls), twored balls resulted:1 time came from box A3 times from box B6 times from box C10 times from box DNotice that from the 40 experiments, 20 result in 2 red balls.From here we have that when drawing 2 red balls the probability that it camefrom a box containing 2 red balls (box A), 3 red balls (box B), 4 red balls (box C)or 5 red balls is:P(A) = 1/20 = 0.05 = 5%P(B) = 3/20 = 0.15 = 15%P(C) = 6/20 = 0.30 = 30%P(D) = 10/20 = 0.50 = 50%

One of the boys leaves the ball in the box and takes the box with him.

Yes, in Henry V. The Dauphin of France, thinking that Henry is a worthless fribble as he appeared to be when he was Prince Hal (in the Henry IV plays) sends as compensation for the English claims to the throne of France a box of tennis balls (which he calls a treasure chest), implying that Henry is probably more interested in tennis than politics. Big mistake. The tennis balls just make Henry mad and more convinced than ever to start a war with France.
If they are standard American pool balls with a 2.25" diament, you can fit 4,529,370 balls in a 25 cubic foot box.
Yes, the plastic box filled with tennis balls will sink deeper than the empty plastic box. This is because the filled box has more mass and therefore displaces more water, which increases its overall weight and makes it sink further.
The surface area would increase by x16, e.g. 2x2x2 box= 24cm squared 8x8x8 box= 384cm squared :384/24=16
If every box contained 11 balls that would account for only 99 balls. The hundredth ball has to be placed in a box already containing 11 balls...
Some special rules made in tennis is that if the ball bounces on your box you will be out.
I am thinking the anser is 5/8... hope it helps
