Answer:
probability = 0.008
probability = 0.0256
Explanation:
we know here probability of defective is 0.2
so probability of not defective is 1 - 0.2 = 0.8
as we know 3 item is arrive off process line in succession
so The probability that an item is defective is
as P(defective) = 0.20
as all item are independent so
probability that all three items are defective is
probability = 0.20 × 0.20 × 0.20 = 0.008
and
probability that exactly 3 of next 4 are defective
so number of way that can choose 3 out of 4 is
= 
= 4
so as all are independent probability is
probability = ( the number of way to choose 3 out of 4 ) × ( 3 item defective ) × ( 1 item not defective )
probability =
× 0.2³ × ( 1- 0.2)
probability = 4 × 0.008 × 0.8
probability = 0.0256
<h2>The security system will alert authorities and deter criminals, protecting your valuables and property.
</h2><h2>The security system will give you peace of mind</h2>
Explanation:
Option 1: We cannot say that every visitor will be a thief or criminal. So a "home security system" is to stay alert from danger
Option 2: Burglars and home security system is to alert authorities and to protect our valuables. But home security system in addition can detect flood, fire, etc.
Option 3: Yes that's true. We feel like there is someone to protect us and our valuables. So it provides peace of mind.
Option 4: Why should we keep the doors unlocked? It will tempt for crime to happen. So this choice is invalid.

Answer:
5.4%
Explanation:
Several years ago the Haverford Company sold a $1,000 par value bond that now has 25 years to maturity and an 8.00% annual coupon that is paid quarterly. The bond currently sells for $900.90, and the company’s tax rate is 40%. What is the component cost of debt for use in the WACC calculation
Face value of bond = coupon amount / interest rate
1000 = 80 / 8%
Therefore 900.9 = 80 / revised interest rate
multiply both sides by the 'revised interest rate
revised interest rate x 900.9 = 80
Hence, revised interest rate = 80 / 900.9 = 9%
Secondly if the company’s tax rate is 40%, the component cost of debt for use in the WACC calculation = kd (1 - t)
where:
kd = Cost of debt
t = tax rate
Therefore cost of debt for use in the WACC calculation = 9% (1-0.4) = 5.4%
