Answer:
0.6804
Step-by-step explanation:
Given that Margie is practicing for an upcoming tennis tournament. Her first serve is good 20 out of 30 times on average.
Since each trial is independent and there are two outcomes, X no of good serves is binomial with n=6 and p =2/3
Required probability
= Prob that atleast four of 6 times good serve
=![P(X\geq 4)](https://tex.z-dn.net/?f=P%28X%5Cgeq%204%29)
=![P(x=4,5 or 6)\\=1-F(3)\\=0.6804](https://tex.z-dn.net/?f=P%28x%3D4%2C5%20or%206%29%5C%5C%3D1-F%283%29%5C%5C%3D0.6804)
Formula used:
P(X=r) =![6Cr (\frac{2}{3}^r )(\frac{1}{3}^{6-r} )](https://tex.z-dn.net/?f=6Cr%20%28%5Cfrac%7B2%7D%7B3%7D%5Er%20%29%28%5Cfrac%7B1%7D%7B3%7D%5E%7B6-r%7D%20%20%29)
You can not "solve" this, so to speak, rather simplify this expression. Take the "2" and multiply that by the "a" and the "3" in the parentheses. You will then have the simplified answer of: 2a times 6.
Hope that helps!
Given Information:
Years = t = 35
Semi-annual deposits = P = $2,000
Compounding semi-annually = n = 2
Interest rate = i = 6.5%
Required Information
Accumulated amount = A = ?
Answer:
Accumulated amount = $515,827
Step-by-step explanation:
The future value of amount earned over period of 35 years and interest rate 6.5% with semi-annual deposits is given by
FV = PMT * ((1 + i/n)^nt - 1)/(i/n))
Where
n = 2
i = 0.065
t = 35
FV = 2000*((1 + 0.065/2)^2*35 - 1)/(0.065/2))
FV = 2,000*(257.91)
FV ≈ $515,827
Therefore, Anthony will have an amount of $515,827 when he retires in 35 years.
