Q3. A bag contains 7 red balls and 3 green balls. A ball is taken out replaced.
ycow [4]

Part (a)

There are 7 red out of 7+3 = 10 total

<h3>Answer: 7/10</h3>

==========================================================

Part (b)

We have 3 green out of 10 total

<h3>Answer: 3/10</h3>

==========================================================

Part (c)

3/10 is the probability of getting green on any selection. This is because we put the first selection back (or it is replaced with an identical copy)

So (3/10)*(3/10) = 9/100 is the probability of getting two green in a row.

<h3>Answer: 9/100</h3>

==========================================================

Part (d)

Similar to part (c) we have 7/10 as the probability of getting red on each independent selection.

(7/10)*(7/10) = 49/100

<h3>Answer: 49/100</h3>

==========================================================

Part (e)

7/10 is the probability of getting red and 3/10 is the probability of getting green. Each selection is independent of any others.

(7/10)*(3/10) = 21/100

<h3>Answer: 21/100</h3>

==========================================================

Part (f)

We have the exact same set up as part (e). Notice how (7/10)*(3/10) is the same as (3/10)*(7/10).

<h3>Answer: 21/100</h3>

What are the solutions to the quadratic equation -2x^2 + 6x + 3 = 0?
mario62 [17]

For this, we will be using the quadratic formula, which is x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}, with a=x^2 coefficient, b=x coefficient, and c = constant. Our equation will look like this: x=\frac{-6+/-\sqrt{6^2-4*(-2)*3}}{2*(-2)}


Firstly, solve the multiplications and the exponents: x=\frac{-6+/-\sqrt{36+24}}{-4}


Next, do the addition: x=\frac{-6+/-\sqrt{60}}{-4}


Next, your equation will be split into two: x=\frac{-6+\sqrt{60}}{-4},\frac{-6-\sqrt{60}}{-4} . Solve them separately, and your answer will be x=-0.436,3.436
