Types of bonds are divided into three categories: good risk, medium risk, and poor risk. Assume that of a total of 13,838 bonds, 7,035 are good risk, 1,388 are medium risk, and the rest are poor risk. One bond is chosen is chosen at random. what is the probability that the bond is not a poor risk? Write only a number as your answer. Round to two decimal places (for example: 0.43). Do not write as a percentage.
Pls help!!
To find the probability that the bond is not a poor risk, we need to calculate the number of bonds that are not poor risk and divide it by the total number of bonds.
The number of bonds that are not poor risk is the sum of the good risk and medium risk bonds: 7,035 + 1,388 = 8,423.
The total number of bonds is given as 13,838.
So, the probability that the bond is not a poor risk is: 8,423 / 13,838 = 0.61 (rounded to two decimal places).
Therefore, the probability that the chosen bond is not a poor risk is 0.61.
To find the probability that the chosen bond is not a poor risk, we need to determine how many bonds are considered poor risk and subtract that from the total number of bonds.
Given that there are a total of 13,838 bonds and the question states that 7,035 are good risk and 1,388 are medium risk, we can calculate the number of poor risk bonds by subtracting the sum of good and medium risk bonds from the total number of bonds:
Number of poor risk bonds = Total number of bonds - Number of good risk bonds - Number of medium risk bonds
Number of poor risk bonds = 13,838 - 7,035 - 1,388 = 5,415
Now, to find the probability of not choosing a poor risk bond, we divide the number of bonds that are not poor risk by the total number of bonds:
Probability of not choosing a poor risk bond = Number of bonds not poor risk / Total number of bonds
Probability of not choosing a poor risk bond = (Total number of bonds - Number of poor risk bonds) / Total number of bonds
Probability of not choosing a poor risk bond = (13,838 - 5,415) / 13,838
Probability of not choosing a poor risk bond ≈ 0.6108
Therefore, the probability that the chosen bond is not a poor risk is approximately 0.61.
.61
How many are NOT poor risk?
divide that by 13838 , the total bonds
round to 2 decimals
(looks like we just have to follow the instructions)
