Answer:

The answer is " $0.99999340657 \sim 1$ ".

Step-by-step explanation:

$Sucess \ probability \ (p) = 94\% \ or\ 0.94\\\\Sample\ numbers\ n = 14\\$

Using formula:

$P(X=r)= ^n C_r \times p^r \times (1-p)^{n-r}$

Let

$\to r=8,9,10,11,12,13 \ or\ 14\\\\$

Substituting the value for all r:

$P(X=8)= 0.00008540547\\\\P(X=9)= 0.00089201264\\\\P(X=10)= 0.00698743233\\\\P(X=11)= 0.03980719025\\\\P(X=12)= 0.15591149513\\\\P(X=13)= 0.37578668058\\\\P(X=14)= 0.42052319017\\$

Therefore,

$P(X>7)= P(X=8)+P(X=9)+....P(X=14)\\\\= 0.99999340657 \sim 1.$

Find the proceeds for the simple discount note.

Ronch [10]

Given:
<span>Face value $4,530,
discount rate 7.2%,
time 125 days

Discount on Simple Discount note:
Discount = Maturity Value * discount rate * term
Discount = 4,530 * 0.072 * 125/360
Discount = 113.25

Proceeds for the simple discount note
Proceeds = Maturity Value - Discount
Proceeds = 4,530 - 113.25
Proceeds = 4,416.75

The proceeds for the simple discount note is $4,416.75</span>
