"if n balls are distributed randomly into k urns, what is the probability that the last urn contains j balls?"
seraphim [82]

The answer relies on whether the balls are different or not. If they are not, which is almost certainly what is intended.


If they are, the perceptive is a bit different. Your expression gives the likelihood that a particular set of j balls goes into the last urn and the other n−j balls into the other urns. But there are (nj) different possible sets of j balls, and each of them the same probability of being the last insides of the last urn, so the total probability of completing up with exactly j balls in the last urn is if the balls are different.


See attached file for the answer.

Convert the function into intercept form. Show your work. y=-x^2+5x+36
UkoKoshka [18]
Y = -x2 + 5x + 36 <span>→ y = -(x2 -5x -36)


</span><span>→ y =  -(x2 - 9x +4x - 36)


</span><span>→ y = -[x(x-9) + 4(x - 9)]


</span><span>→ y = -(x - 9)(x + 4)

Your answer would be </span>y=-(x-9)(x+4).

A right cylinder ice cream cone has 600 cubic centimeters of ice cream, what is the radius of the cone of the height is 15 centi
choli [55]
The formula for volume is V=Bh where  B is the area of the base. 
plug in what they have given you:
600=B(15) you can divide both sides by 15

40=B    We know that a cylinder's base is a circle so we can use the area f                           formula for a circle to solve for the radius.
40 = pi(r)^2   divide both sides by pi to get the r^2 alone
40/pi=r^2     square root both sides to get rid of the square
you should get
r=3.5 approximately
