How many ways are there to put 6 balls in 3 boxes if three balls are indistinguishably white, three are indistinguishably black,
erik [133]
Let the boxes be Box 1, Box 2, Box 3. 

consider the 3 white balls. They can be all of them in one box:

(3, 0, 0) (3 in Box 1, 0 in box 2 and 0 in box 0)
(0, 3, 0)
(0, 0, 3)

We can have 2 in one box, and 1 in one of the remaining boxes:

(2, 0, 1)
(2, 1, 0)
(0, 2, 1)
(1, 2, 0)
(0, 1, 2)
(1, 0, 2)

and there is only one way: (1, 1, 1) to place one white ball in each box

In total there are: 3+6+1=10 ways to place the white balls. Similarly there are 10 ways to place the black ones.

Since every placement of the white balls can be combined with any placement of the black balls, there are 10*10=100 ways to place the 3white balls and the 3 black bals in the boxes.

I need help for the solution​
Sonja [21]

Answer:

\boxed{ \ dY_t=(2\theta+2\psi Y_t+\phi^2)dt+2\phi \sqrt{Y_t}dW_t\ }

Step-by-step explanation:

it is a long time I have not applied Ito's lemma

I would say the following

for f(x)=x^2

f'(x)=2x

f''(x)=2

so using Ito's lemma we can write that

dY_t=2V_tdV_t+\phi^2dt

dY_t=2(\theta+\psi V_t^2)dt+2\phi V_tdW_t+\phi^2dt

dY_t=(2\theta+2\psi V_t^2+\phi^2)dt+2\phi V_tdW_t

so it comes

dY_t=(2\theta+2\psi Y_t+\phi^2)dt+2\phi \sqrt{Y_t}dW_t

A special deck of cards has ten cards. Four are green, three are blue, and three are red. When a card is picked, its color of it
nata0808 [166]

Answer:

P(A) = 3/20

Step-by-step explanation:

P(A)=P(blue)P(head)=(3/10)(1/2)=3/20

as there are 10 cards in total, out of which 3 are blue so the probability to get the blue card is, P(blue) = 3/10. and the probability of getting a head when a coin is tossed is P(head) = 1/2.

So in total

P(A) = P(blue)*p(head) = (3/10)*(1/2) = 3/20 = 0.15

If the base of a triangle is 20mm and the area of the triangle is 40m2. then what will be the height and how can we find it​
Eddi Din [679]

Use the formula for area of a triangle:

Area = 1/2 x base x height.

Fill in what you know:

40 = 1/2 x 20 x height

Multiply both sides by 2:

80 = 20 x height

Divide both sides by 20

Height = 4 m
