Answer:
a) There is a 66.7% chance that you were given box 1
b) There is a 80% chance that you were given box 1
Step-by-step explanation:
To find this, we need to note that there is a 1/10 chance of getting a defective bulb with box 1 and a 1/20 chance in box 2.
a) To find the answer to this, find the probability of getting a defective bulb for each box. Since there is only one bulb pulled in this example, we just use the base numbers given.
Box 1 = 1/10
Box 2 = 1/2
From this we can see that Box 1 is twice as likely that you get a defective bulb. As a result, the percentage chance would be 2/3 or 66.7%
b) For this answer, we need to square each of the probabilities in order to get the probability of getting a defective one twice.
Box 1 = 1/10^2 = 1/100
Box 2 = 1/20^2 = 1/400
As a result, Box 1 is four times more likely. This means that it would be a 4/5 chance and have a probability of 80%

Okay hold on. I’m trying to figure this question out. I will help you!
Answer:
5%
Step-by-step explanation:
Solving our equation
r = 4537.5 / ( 9075 × 10 ) = 0.05
r = 0.05
converting r decimal to a percentage
R = 0.05 * 100 = 5%/year
The interest rate required to
accumulate simple interest of $ 4,537.50
from a principal of $ 9,075.00
over 10 years is 5% per year.
