(9/18)(9/18) = 81/324. The probability that Amy takes out pink chips in both draws is 81/324.

In this example we will use the probability property P(A∩B), which means given two independent events A and B, their joint probability P(A∩B) can be expressed as the product of the individual probabilities P(A∩B) = P(A)P(B).

The total number of chips of different colors in Amy's bag is:

8 blue chips + 9 pink chips + 1 white chip = 18 color chips

Amy takes out a chip from the bag randomly without looking, she replaces the chip and then takes out another chip from the bag.

So, the probability that Amy takes out a pink chip in the first draw is:

P(A) = 9/18 The probability of takes out a pink chip is 9/18 because there are 9 pink chips in the total of 18 color chips.

Then, Amy replaces the chip an takes out another which means there are again 18 color chips divide into 8 blue chips, 9 pink chips, and 1 white chip. So, the probability of takes out a pink chip in the second draw is:

P(B) = 9/18 The probability of takes out a pink chip is 9/18 because there are 9 pink chips in the total of 18 color chips.

What is the probability that Amy takes out a pink chip in both draws?

P(A∩B) = P(A)P(B)

P(A∩B) = (9/18)(9/18) = 81/324

2x+3y= 14 3х - 4 y = 4

goldenfox [79]

The solution to given system of equations are (x, y) = (4, 2)

Solution:

Given system of equations are:

2x + 3y = 14 ---------- eqn 1

3x - 4y = 4 --------- eqn 2

We have to solve the given system of equations

We can solve the above system of equations by elimination method

Multiply eqn 1 by 3

3(2x + 3y = 14)

6x + 9y = 42 --------- eqn 3

Multiply eqn 2 by 2

2(3x - 4y = 4)

6x - 8y = 8 ----------- eqn 4

Subtract eqn 4 from eqn 3

6x + 9y = 42

6x - 8y = 8

( - ) --------------

9y + 8y = 42 - 8

17y = 34

Substitute y = 2 in eqn 1

2x + 3(2) = 14

2x + 6 = 14

2x = 14 - 6

2x = 8

Thus the solution to given system of equations are (x, y) = (4, 2)
