Answer:
Zero
Step-by-step explanation:
The probability of the ball being red after first selection is = (r) ÷ (r+b)
The probability of the ball being blue after first selection is = (b) ÷ (r+b)
If the ball selected is red, the total number of balls after its returned together with m number of red balls is = r+b+m
The probability of the selection doesn't depend on the second selection, hence condition probability is zero.
However the probability of the second selection depends on the first selection.
