Answer:
1.27%
Step-by-step explanation:
To solve this problem, we may consider a binomial distribution where a customer can either accept or reject (and return) the diskette package.
Lets consider some aspects:
1. From the formulation of the exercise we know that a package is accepted if it has at most 1 defective diskette. So our event A is defined as:
A = 0 or 1 defective diskette
2. The probability of a diskette being defective is 0.01
3. Each package contains 10 diskettes.
If X is defined as number of defective diskettes in the package, the probability of X is given by a binomial distribution with probability 0.01 and n=10
X ~ Bin(p=0.01, n=10)
Let us remember the calculation of probability for the binomial distribution:
with x = 0, 1, 2, 3,…, n
Where
n: number of independent trials
p: success probability
x: number of successes in n trials
In our case success means finding a defective diskette, therefore
n=10
p=0.01
And for x we just need 0 or 1 defective diskette to reject the package
Hence,
with x = 0, 1
So,
Now, because we have 3 packages and we might reject just 1 of them, we can find this probability like this:
Finally, we have that the probability of returning exactly one of the three packages is 1.27%
Answer:
She have 345$ in her account.
Step-by-step explanation:
Given that,
Ellen has $75 in her savings account she deposits 25 every week her father also deposit 35 into the account every time Ellen most salon
Suppose, her savings account balance can be shown with the following expression:
75 + 25w + 35m
If Ellen saves for 8 weeks and most the salon 2 times, how much will she have in her account.
We know that,
When the numbers appear with variables it called coefficients.
When the numbers appear without variables it called constant.
Alphabets in an expression are called variables.
According to question,
25 and 35 are the coefficients and the number 75 appear without variables.
We need to calculate the balance in her account
Using expression
Put the value in the expression
Hence, She have 345$ in her account.
