We have two urns A and B. Urn A contains 4 red balls and 3 blue balls. Urn B is empty. We randomly draw two balls X1 and X2 without replacement from urn A and put them into urn B. Then we draw two balls Y1 and Y2 randomly with replacement from urn B. 1. Given that Y1 and Y2 have the same color, what is the probability that X1 and X2 have the same color

Option 'b' is correct.

Step-by-step explanation:

Since we know that a bar graph can be displayed in many different ways:

1) Simple bar graph : It used bars to display comparison between the categories of data.

2) Composite bar graph : It is a special type of bar graph to display multiple data comprised in a single row or column.

3) Histogram : It is a special type of bar graphs to uses frequency of numerical data to show the comparison between the categories of data.

4) Scatter plot graph : It is a two dimensional data uses dots to represent the values for two different variables, i.e. one plotted along y-axis and the other plotted along x-axis.

So, it uses dots rather than using bars.

Hence, Scatterplot graph is not represent a bar graph.

Thus, Option 'b' is correct.
