Answer:

  • Total number of red marbles = 10 red marbles.
  • Total number of blue marbles = 5 blue marbles.
  • Total Number of white marbles = 5 white marbles.

Step-by-step explanation:

The bar shows the following information that can we fetch to solve the problem.

  • Red marbles drawn nearly 50% of the time
  • Blue marbles drawn nearly 25% of the time
  • White marbles drawn nearly 25% of the time

Predicting how many are red marbles:

If there are 20 marbles in the bag, it logically means that each marble, averagely, should likely be drawn 5% of the time.

As the bar shows that Red marbles drawn nearly 50% of the time, it means that we will have to divide 'Red marbles drawn nearly 50% of the time" by the " each marble from 20 marbles be drawn 5% of the time".

So,

Total number of red marbles = 50% / 5% = 10 red marbles.

Predicting how many are blue marbles:

If there are 20 marbles in the bag, it logically means that each marble, averagely, should likely be drawn 5% of the time.

As the bar shows that blue marbles drawn nearly 25% of the time, it means that we will have to divide 'blue marbles drawn nearly 25% of the time" by the " each marble from 20 marbles be drawn 5% of the time".

So,

Total number of blue marbles = 25% / 5% = 5 blue marbles.

Predicting how many are white marbles:

If there are 20 marbles in the bag, it logically means that each marble, averagely, should likely be drawn 5% of the time.

As the bar shows that white marbles drawn nearly 25% of the time, it means that we will have to divide 'white marbles drawn nearly 25% of the time" by the " each marble from 20 marbles be drawn 5% of the time".

So,

Total number of white marbles = 25% / 5% = 5 white marbles.
