If two marbles are selected at random with replacing between draws, what is the probability that the outcome is red then yellow?

saul85 [17]

The probability that the outcome is red then yellow is 0.036.

Given that in a jar there are 8 red marbles, 1 yellow marble and 6 green marbles.

We are required to find the probability of obtaining a red then yelow marble if two marbles are drawn and replacement is used.

Probability is the calculation of finding the chance of happening a event among all the events possible. It lies between 0 and 1.

Probability=Number of items/ Total items.

Number of red marbles=8

Number of yellow marble=1

Number of green marbles=6

Total marbles=15

Probability of obtaining red marble=8/15

Probability of obtaining yellow marble=1/15 (Because replacing is there so the number of total marbles do not decrease)

Required probability=8/15*1/15

=8/225

=0.035555

After rounding off we will get 0.036.

Hence the probability that the outcome is red then yellow is 0.036.

Question is incomplete. The following line should be included in question:

A jar contains 8 red marbles , a yellow marble and 6 green marbles.

Can you solve r=4+7x-sx for x

Nata [24]

R = 4 + 7x -sx
7x - sx = r - 4
x (7 -s) = r - 4
x = r -4 / 7 - s
if we know the value of s and r, we can find the value of x.
there is another way to solve this equation:
r = 4 + 7x - sx
7x - sx = r - 4
7x - sx - (r - 4) = 0
if we put 7x - sx in plce of r - 4, we get
7x - sx - (7x - sx) = 0
7x - sx -7x +sx = 0
Now 7x- 7x = 0 and sx - sx = 0
So all the terms gives the answer 0
the solution o this equation could not be determined.

∠A and \angle B∠B are vertical angles. If m\angle A=(8x-4)^{\circ}∠A=(8x−4) ∘ and m\angle B=(7x+3)^{\circ}∠B=(7x+3) ∘ , then fin

Zolol [24]

Answer:

∠B = 52°.

Step-by-step explanation:

Given: m∠A=(8x-4)° and m∠B=(7x+3)°. ∠A and ∠B are vertical angles.

Since ∠A and ∠B are vertical angles. So, there measure are equal.

$m\angle A=m\angle B$
