KATRIN_1 [288]

Answer:

Step-by-step explanation:

Given

Jar contains 4 white and 4 black marbles

We randomly select 4 marbles out of which 2 are white and 2 are black

Probability that 2 white and 2 black marbles are selected is

$P=\frac{^4C_2\times ^4C_2}{^8C_4}$

$P=\frac{18}{35}$

The process is continue for n trails until we choose the correct order

i.e. we have to fail in n-1 trails

For exact n selection Probability is given by

$Req.\ Probability=Probability\ of\ failure\ in\ (n-1)\ trials\times Probability\ of\ getting\ exact\ order$

$=\left ( 1-\frac{18}{35}\right )^{n-1}\times \frac{18}{35}$

-6×-15=4×+35 i need help with this problem

Burka [1]

Isolate the variable by dividing each side by factors that don't contain the variable.

-6x-15+15=4x+35+15

-6x=4x+50
(Subtract 4 on both sides)

-10x=50
(Divide by 10 on both sides)

x=5
