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.
Answer:
D (x,y) ---> (x + 1, y - 6)
Step-by-step explanation:
The triangle in blue moves 1 unit to the right, and 6 units down.
The answer is B. 16 because you multiply 4 with 2s and -1 so the new equation will be 8s-4=7s+12 and you have to subtract the variable 7s to 8s the equation will be 1s-4=12 and add 4 to 12 and it gives you 16 and just divide 16 and one and you answer should be 16. :)
