Solution: Telemarketing. the probability that a call will reach a live person is 0.2. the calls are independent. (a) a telemarketer places 5 calls. what is the probability that none of them reaches a live person.
Answer: The given random experiment can be considered as binomial experiment with probability of success = 0.2 and number of trials = 5
Therefore, we have:

Let x be the number calls that reach to live person.
We have to find 
Using the binomial probability distribution, we have:



Therefore, the probability that none of them reaches a live person is 0.3277

- Height & Area of the given parallelogram
✰ 
In right angled triangle ABE :
- Hypotenuse ( h ) = 8
- Perpendicular ( p ) = h [ height ]
= 20°
Now , Using trigonometric ratio :

Plug the known values :
⟶ 
⟶ 
⟶ 
⟶ 
Now , We have :
- Base ( b ) = 15
- Height ( h ) = 2.72
Finding the area of a parallelogram whose base and height are 15 and 2.72 respectively :
❀ 
⟶ 
⟶ 
Hence , Our final answer :
