The probability of drawing two green marbles, with replacement is \frac{9}{25}

<h3><u>Solution:</u></h3>

Given that There are 4 red and 6 green marbles in a jar

<em><u>To find: probability of drawing two green marbles, with replacement</u></em>

The probability of an event is given as:

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

Here total number of possible outcomes = 4 red + 6 green marbles = 10

Favourable outcome is drawing two green marbles with replacement

So favourable outcome = 6

<em><u>So probabilty of choosing green marble:</u></em>

probability = \frac{6}{10} = \frac{3}{5}

Now given that with replacement, so we get

\text { probability }=\frac{3}{5} \times \frac{3}{5}=\frac{9}{25}

Thus probability is \frac{9}{25}

What is the measure of an angle if it is 260 degrees less than six times its own complement?
poizon [28]

Answer:

40 degrees

Step-by-step explanation:

Complementary angles have a sum of 90.

y = 90 - x

The angle is 260 degrees less than six times its complement.

y = 6x - 260

90 - x = 6x - 260

350 - x = 6x

350 = 7x

50 = x

This is the measure of the complement.

y = 90 - x

y = 90 - 50

y = 40

This is the measure of the first angle.
