The complete question is in the picture, please refer to the attached picture.
Total number of marbles = 4 + 3 + 3 = 10
Number of blue marbles = 3
Number of red marbles = 4
P(blue) = 3/10
P(red) = 4/10 = 2/5
Thus, the total number of marbles is 10, the number of blue marbles is 3, and the red marbles are 4.
