laiz [17]

Answer:

P(R_2Y_2C_2B_2) = 0.03845

Step-by-step explanation:

Given

Balls = 4 --- [R, Y, C and B]

Turns = 8

Required

P(R_2Y_2C_2B_2)

Since each of the 4 balls are equally likely, their probability is:

P(R) = P(Y) = P(C) = P(B) = \frac{1}{4}

From P(R_2Y_2C_2B_2), we have:

R = Y = C = B = 2

Total = 8

So, the total arrangement of the 8 balls is:

Arrangement = \frac{8!}{2!2!2!2!}

Arrangement = \frac{40320}{2*2*2*2}

Arrangement = \frac{40320}{16}

Arrangement = 2520

The individual probability of each ball, when put together is

Probability = P(R)^2 * P(Y)^2 * P(C)^2 * P(B)^2

Probability = (1/4)^2 *(1/4)^2 *(1/4)^2 *(1/4)^2

Probability = (1/16) *(1/16) *(1/16) *(1/16)

Probability = \frac{1}{65536}

Lastly:

P(R_2Y_2C_2B_2) = Arrangement * Probability

P(R_2Y_2C_2B_2) = 2520 * \frac{1}{65536}

P(R_2Y_2C_2B_2) = \frac{2520 }{65536}

P(R_2Y_2C_2B_2) = 0.03845
