A box has 1 red marble, 1 blue marble and 4 green marbles of the same shape and size. Dan draws a marble randomly from the box , replaced it, and then draws another marble randomly. What is the probability of drawing two green marbles in a row? Explain your answer.

4/9

Step-by-step explanation:

The total number of marbles is 1+1+4 = 6

1 red marble, 1 blue marble and 4 green marbles

1st draw:

P(green) = green / total = 4/6 = 2/3

Replace the marble

The total number of marbles is still 6

1 red marble, 1 blue marble and 4 green marbles

2nd draw:

P( green) = green / total = 4/6 = 2/3

P( green, replace, green) = 2/3 * 2/3 = 4/9

(2/6)(2/6)= (2/3) or .67777...

Step-by-step explanation:

This is a simple probabilty problem using replacement meaning you would not take away anything from the total formula i used was green/ total times green/ total

6.9

step-by-step explanation:

simple math really

6 1/2 times 0.6 = 3.9

but if you are just doing 6 and not 6 1/2 then the answer is 3.6
