Answer this question and show the workout
saul85 [17]

Step-by-step explanation:

Ace:

15800 x (-2/100) = -316

15800 - 316 = 15485

Beta:

17425 x (-3/100) = -522.75

17425 - 522.75 = 16902.25

Carro:

21280 x (-1.5/100) = -319.2

21280 - 319.2 = 20960.8

Delta:

24172 x (-1.8/100) = -435.096

24172 - 435.096 = 23736.90

Types of bonds are divided into three categories: good risk, medium risk, and poor risk. Assume that of a total of 11, 332 bonds
Alekssandra [29.7K]

Answer:

Probabilty of not poor= 0.75

Step-by-step explanation:

total of 11332 bonds.

7311 are good risk.

1182 are medium risk.

Poor risk

= total risk-(good risk+ medium risk)

= 11332-(7311+1182)

= 11332-8493

= 2839.

Poor risk = 2839

Probabilty that the ball choosen at random is not poor= 1 - probability that the ball is poor

Probability of poor = 2839/11332

Probabilty of poor= 0.2505

Probabilty that the ball choosen at random is not poor= 1- 0.2505

= 0.7495

To two decimal place= 0.75
