There is a bag filled with 3 blue, 4 red and 5 green marbles. A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 greens?

the probability of getting two greens is 25/144

Brainliest is always aprreciated :)

Step-by-step explanation:

Since there are 12 marbles total and there are 5 green marbles the chance of getting 2 greens would be 5/12.

(since it's already in simplest form we keep it as 5/12)

Since we put the marble back we have the same chance the second time being 5/12.

The marble selections are independent and you can multiply the two probabilities to get the following:

probability of getting 2 reds =( 5/12)^2

(5/12)^2 = 25/144

So the probability of getting two greens is 25/144

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
