- Turning on time be x
- Turning of time be y
If 19:00<=x<=19:30 and 4:00<=y<=6:00
Total time difference

- In order to mange time between 9--10 hours 30 minutes should be deducted in pairs from starting and ending .By which net deduction i e x-y=0
- Total starting options=x=15
- Total ending options=x=15
- Sample space=|S|=15+15=30
- E=1

Answer:
31.77% probability the surgery is successful for exactly five patients.
Step-by-step explanation:
For each patient, there are only two possible outcomes. Either the surgery is successful, or it is not. The probability of the surgery being successful for a patient is independent of other patients. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
A surgical technique is performed on seven patients.
This means that 
You are told there is a 70% chance of success.
This means that 
Find the probability the surgery is successful for exactly five patients.
This is P(X = 5).

She read nine chapters each hour
It’s an acute angle, but is almost a right angle. it isn’t a right angle because right angles are 90° , and usually have a box to show it.
