Answer:
(mn+n²)/(m+n)
Step-by-step explanation:
probability of blue marble= n/(n+m)
probability of red marble= m/(n+m)
probability that process stops = Probability of both blue + probability of both red= n/(n+m) × n/(n+m) + m/(n+m)×m/(n+m)
= (n²+m²)/(n+m)²
P(1st marbel is blue)= P(blue and red) + P(blue and blue)
= mn/(n+m) + n²/(n+m)
= (mn+n²)/(m+n)
P(1st marble is blue | process stops)= ( (mn+n²)/(m+n)× (n²+m²)/(n+m)²)/ ((n²+m²)/(n+m)²)
= (mn+n²)/(m+n)
Answer:
repeating decimal
Step-by-step explanation:
1/6=0.166666666 and it keeps on going
I believe the answer should be 102. It has been a long time since I have done one of these but I believe that if you times the outside angle by 2 then it is the angle if the point were to be in the center.
Answer:
Step-by-step explanation:
Common ratio r = a₂/a₁ = -4/(½) = -8
nth term = a₁rⁿ⁻¹ = ½(-8)ⁿ⁻¹
This can be further simplified to (-1)ⁿ⁻¹2³ⁿ⁻⁴
