it depends how many blue marbles there are and how many marbles total.

56 marbles (TOTAL)

The probability of selecting 4 red marbles or 5 blue marbles depends on how many marbles there are altogether, and how many of the total number of marbles are red and how many are blue.

Number of marbles in total = 90 Fraction of marbles are blue = five-ninth Number of blue marbles = five-ninth of ninety = 50 So, the answer is 50 blue marbles.

700 bags if each bag contains 8 marbles is a total of 5600 marbles.

Number of possibilities for one category / Total of all possibilities. For example, if I had a bag of marbles where there are three white marbles and two black marbles. The probability of pulling out a white marble is how many white marbles are in the bag which is: three. But the total of things you can draw out of the bag can either be one of the three white marbles or one of the two black marbles. 3 white marbles+ 2 Black marbles= five marbles. Possibility is 3/5 for drawing a white marble.

The same as the total momentum before the collision.
