Box A contains 1 black and 3 white marbles, and box B contains 2 black and 4 white marbles. A box is selected at random, then a

Anna11 [10]

Answer: Probability that Box A was chosen given that black marble is chosen is 0.5.

Step-by-step explanation:

Since we have given that

Number of boxes = 2

In Box A,

Number of black marbles = 1

Number of white marbles = 3

In Box B,

Number of black marbles = 2

Number of white marbles = 4

Since black marble is selected.

So, using Bayes theorem , we get that

$P(E_1|B)}=\dfrac{P(E_1).P(B|E_1)}{P(E_1).P(B|E_1)+P(E_2).P(E_2|B)}\\\\P(E_1|B)=\dfrac{0.5\times \dfrac{1}{3}}{0.5\dfrac{1}{3}+0.5\times \dfrac{2}{6}}\\\\P(E_1|B)}=\dfrac{0.167}{0.167+0.167}\\\\P(E_1|B)}=0.5$

Hence, probability that Box A was chosen given that black marble is chosen is 0.5.

-1.2x + 11.45 = 8.21

kondaur [170]

Hi there!

If you solve for $x$ in this problem you would end up with a result of $\boxed{x = 2.7}$ . To find $x$ you need do the following:

First, subtract 11.45 from both sides:

$-1.2x+11.45-11.45=8.21-11.45$

$-1.2x=-3.24$

Next, divide both sides by -1.2:

$\frac{-1.2x}{-1.2} = \frac{-3.24}{-1.2}$

To get the end result of:

$\boxed{x = 2.7}$
