The probability for choosing green and red is \frac{1}{12}

<u>Solution:</u>

Given that , A bag contains 1 red, 1 yellow, 1 blue, and 1 green marble.

We have to find what is the probability of choosing a green marble, not replacing it, and then choosing a red marble?

Now, we know that,

\text { probability of an event }=\frac{\text { number of favourable outcomes }}{\text { total number of outcomes }}

So, total possible outcomes = 1 red + 1 yellow + 1 blue + 1 green = 4

\text { Now, probability for green marble }=\frac{1 \text { green marble }}{4 \text { marbles }}=\frac{1}{4}

And now, total outcomes will be only 3 as we are not replacing the picked marble.

\begin{array}{l}{\text { Then, probability for red marble }=\frac{1 \text { red marble }}{3 \text { marbles }}=\frac{1}{3}} \\\\ {\text { Then overall probability }=\frac{1}{4} \times \frac{1}{3}=\frac{1}{12}}\end{array}

Hence, the probability for choosing green and red is \frac{1}{12}

Probability of choosing a green marble, not replacing it, and  then choosing a red marble is \frac{1}{12}

Step-by-step explanation:

We have 1 red, 1 yellow, 1 blue, and 1 green marble in bag

Total Marbles = 4

Probability of choosing green marble= \frac{1}{4}

Since green marble is not replaced i.e it is not put back into the bag, so

Total Marbles = 4-1 = 3

Probability of choosing red marble= \frac{1}{3}

Now, calculating the probability of choosing a green marble, not replacing it, and  then choosing a red marble

= Probability of choosing green marble * Probability of choosing red marble

= \frac{1}{4}*\frac{1}{3}

=\frac{1}{12}

So, probability of choosing a green marble, not replacing it, and  then choosing a red marble is \frac{1}{12}

Answer:

The circle length is 90*pi which should be 3.14

So the circle length is 282.6

The central angle is 90 degree which is 1/4 part of 360 degree

From the theory of arc, the arc length should also be 1/4 part of circle length.

So the answer should be 1/4 * 282.6 = 70.65

Becasue it should be to the nearest tenth, so the answer should be 70.7
