The probability that exactly 6 are defective is 0.0792.
Given:
30% of the bulbs in a large box are defective.
If 12 bulbs are selected randomly from the box.
To find:
The probability that exactly 6 are defective.
Solution:
Probability of defective bulbs is:
Probability of non-defective bulbs is:
The probability that exactly 6 are defective is:
Therefore, the probability that exactly 6 are defective is 0.0792.

Answer:
1. 24
2. 6
3. No
Step-by-step explanation:
The formula for cyclic alkene is , so if it has 12 carbon atoms, it will have double the amount of hydrogen atoms, therefore, 24 hydrogen atoms.
The same works in reverse. If we have 12 hydrogen atoms in this, then there will be half the amount of carbon atoms, therefore 6.
Since the relationship between Carbon and Hydrogen here is double and half, odd numbers can't be divided by 2 and end up with a whole number, so an odd number of hydrogen atoms is not possible.
Hope this helped!
