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:
I think the answer to the second one is D, and that means the first one is purple
Step-by-step explanation:
36.8%. divide 28.52 by 77.5 then multiply by 100
Answer:
Step-by-step explanation:
y - 2 = 30
y = 32
Answer:
Step-by-step explanation:
To find the inverse function switch variables out and solve for y
If
y=(x+3)/x swap variables to get
(y+3)/y=x then solve for y
y+3=yx
y-yx+3=0
y-yx=-3
y(1-x)=-3
y=-3/(1-x)
y=3/(x-1)
