Please help! A hat has the following marbles in it: 5 gray, 3 red, 6 white, 2 yellow and 4 green.
abruzzese [7]

Answer:

1/40

Step-by-step explanation:

Probability: (number of ways to achieve the desired result / number of possible results)

For example, if we want a coin to land on heads:

We know there is one way for it to land on heads and two possible outcomes. Thus, the possibility of flipping a head is 1/2.

Using this, we know that there are 5 grey marbles (the desired result) and there are  (5 + 3 + 6 + 2 + 4) total possible outcomes. The probability of drawing a grey marble is then:

5 / (5 + 3 + 6 + 2 + 4) =

5/20 =

1/4

We also know that there are 2 yellow marbles, so the probability of drawing one would be: 2 / 20 = 1/10

To find the probability of both of these events happening right after each other, multiply the probability of them each happening together.

1/4 * 1/10 = 1/40 chance of picking a grey marble and then a yellow marble.

Sati [7]

Answer:

90% of people marry there 7th grade love. since u have read this, u will be told good news tonight. if u don't pass this on nine comments your worst week starts now this isn't fake. apparently if u copy and paste this on ten comments in the next ten minutes you will have the best day of your life tomorrow. you will either get kissed or asked out in the next 53 minutes someone will say i love you

Step-by-step explanation:

and yes... I can out to my bestfriend of over six years and after me telling her I wasn't ready to come our completely she outed me to several people without my permission. This resulted in her very religious mother telling my very religious father as well as many other people. It was not only hurtful but wrong. I got my phone taken along with many of my friends numbers that I lost causing me to struggle with my already diagnosed depression and anxiety being I am homeschooled and now have near to no social interaction at almost 15. I handled this situation by keeping my head up and looking at positive things which did come along, including me getting into an arts high school, me finding more ways to cope, and some other things. I am still upset but have chosen to get over the situation. I also still very gay though so them going through all that did nothing.

Andrew [12]

Answer:

I think it would be 120

Step-by-step explanation:

You add 120+120 and it would equal 240. Then 240 dived by 2 which will equal 120.

(120 + 120)= 240 dived by 2= 120 I might be wrong

GREYUIT [131]

Answer:

\frac{11x}{3y}

Step-by-step explanation:

\frac{7x}{3y} + \frac{12x}{9y}

Make both a single fraction by adding together.

\frac{3(7x) + 1(12x)}{9y}

\frac{21x + 12x}{9y}

\frac{33x}{9y}

Simplify

\frac{3(11)x}{3(3y)}

\frac{11x}{3y}
