Please help me!! a bag contains 18 marbles. there are 6 red marbles, 6 yellow marbles, and 6 green marbles. a marble is drawn at random and returned. then another marble is drawn at random

which statements are true?

A. the expected probability of drawing a green marble first is the same as the expected probability of drawing a green marble second.

B. there are six possible outcomes

C. the probability of drawing a red marble first is the same as not drawing a red marble second

D. the expected probability of drawing a red marble and then a yellow marble is 1/9

E. there are three possible outcomes from drawing the same color twice

F. the probability of drawing a yellow marble and then a yellow marble is 1/6

Step-by-step explanation:

A. False. The probability of drawing a green marble twice is even smaller (It may be true though depending on what the question is asking, if it is asking the chance of drawing a green marble second is the same as the 1st chance, then yes it is True.

B.False

C. False

D.True, 1/3*1/3 (Simplified version of 6/18*6/18) is 1/9

E. False (Although this may be true, again depending on the type of question)

F. False

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

the answer to this question is 3/19
