Pls a bag has 1 red marble, 4 blue marbles, and 3 green marbles. peter draws a marble randomly from the bag, replaces it, and then draws another marble randomly. what is the probability of drawing 2 blue marbles in a row? explain your answer.

Step-by-step explanation:

Given : the number of blue marbles = 4

The total number of blue marbles =

Since , Peter draws a marble randomly from the bag, replaces it, and then draws another marble randomly.

It means that the events of drawing any marble is independent of other events.

The probability of drawing a blue marble :

The probability of drawing 2 blue marbles in a row will be :-

Hence, the required probability =

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
