There are 7 red, 9 blue, 2 yellow and 4 green marbles in a bag. You make 2 draws from the bag without returning the first marble selected back to the bag. What is the possibility you select a yellow then another yellow at random? Question 2 options: 2/22 * 1/21 = 2/462 1/22 * 1/21 = 1/462 1/22 + 1/22 = 2/22 1/22 * 1/22 = 1/484

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
