Answer:
The time will be "3 years".
Step-by-step explanation:
The given values are:
Principle,
P = 5120
Amount,
A = 7290
Rate,
r = 12.5
Time,
n = ?
As we know,
⇒ ![A = P[1+\frac{r}{100} ]n](https://tex.z-dn.net/?f=A%20%3D%20P%5B1%2B%5Cfrac%7Br%7D%7B100%7D%20%5Dn)
On substituting the values, we get
⇒ ![7290=5120[1+\frac{12.5}{100} ]n](https://tex.z-dn.net/?f=7290%3D5120%5B1%2B%5Cfrac%7B12.5%7D%7B100%7D%20%5Dn)
On applying cross-multiplication, we get
⇒ ![\frac{7290}{5120}=[1+\frac{125}{100}\times 100 ]n](https://tex.z-dn.net/?f=%5Cfrac%7B7290%7D%7B5120%7D%3D%5B1%2B%5Cfrac%7B125%7D%7B100%7D%5Ctimes%20100%20%5Dn)
⇒ ![\frac{9}{8}\times 3=[8+\frac{1}{8} ]n](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B8%7D%5Ctimes%203%3D%5B8%2B%5Cfrac%7B1%7D%7B8%7D%20%5Dn)

Answer:
0.81
Step-by-step explanation:
P(success) = 0.9
P(failure) = 1 - 0.9 = 0.1
Binomial probability:
P(X=n) = nCr (0.9)^n (0.1)^r
Here, n=2 and r=0:
P(X=2) = ₂C₀ (0.9)² (0.1)⁰
P(X=2) = 0.81
