Answer:
The probability is 0.081
Step-by-step explanation:
Here, we want to calculate the probability that the 3rd inspection will be defective.
What this means is that the first two would
not be defective.
Probability of having a defective DVD = 10% = 10/100 = 0.1
Probability of not having a defective DVD = 1 -0.1 = 0.9
So the probability of third being defective = Probability of first not defective * Probability of second not defective * Probability of third defective
= 0.9 * 0.9 * 0.1 = 0.081
Answer:
$63
Step-by-step explanation:
- Penny = $0,01
- Nickel = $0.05
- Dime = $0.1
- Quarter= $0.25
- Number of pennies = 6*50 = 300
- Number of nickels = 5*40= 200
- Number of dimes = 4*50= 200
- Number of quarters = 3*40 = 120
<u>Total amount of money:</u>
- 300*0.01+ 200*0.05 + 200*0.1 + 120*0.25 = $63
Answer:
11
Step-by-step explanation:
since 30÷45 = 2/3 then
The space taken by a small book is equal to
the space taken by 2/3 a large book.
…………………………………………………
<u><em>Calculating the number of large book corresponding to 23 small books</em></u> :
= 23×(2÷3) + 3
= 18.333333333333 (large book)
Then ,Kevin can pack the shelf with (at most) : 30 - 19 = 11 more large books
Answer:
Step-by-step explanation:
