For the limit to exist, the limits from either side must also exist and be identical. We have
Since the limits do not match, the overall limit does not exist.
Since the limits do not match, the overall limit does not exist.
Answer:
a. 0.011 or 1.1%
b. 31.56% or 0.3156
c. 99.94% or 0.9994
d. 3.42% or 0.0342
Step-by-step explanation:
Given
Number of multiple choice questions = 100
Probability of success for students who have attended lectures and done their homework = 0.85
a. Using binomial distribution
Probability of correctly answering 90 or more questions out of 100
Since,
In Binomial Distribution
where
and
Probability is therefore 1.1% or 0.011
b. Probability of correctly answering 77 to 83 questions out of 100
The probability is therefore 31.56% or 0.3156
c. Probability of correctly answering more than 73 questions out of 100
The probability is therefore 99.94% or 0.9994
d. Assuming that the student has answered randomly
Probability of success = 1/5 = 0.2
Probability of failure = 1 - 0.2 = 0.8
Probability of answering 28 or more questions correctly
The probability is therefore 3.42%
