Answer:
Step-by-step explanation:
If we approximate the binomial distribution with a normal distribution, we have to apply a correction factor for the fact that we are now dealing with a continuous variable instead of a discrete one, as it was with the binomial distribution.
The probability of no more than 35 defective CDs: P(X<35)
In this case, as X=35 is not included in the interval, we start the interval from X=35-0.5=34.5.
being Pb the probability under the binomial distribution and Pn the probability under the normal distribution.
The area for the normal distribution is the one below X=34 (or P(X<34)).
The most exact answer would be 0.19951% but the approximate answer would be 0.2%.
Answer:
Option A
Step-by-step explanation:
By definition, tan∅=opposite/adjacent, so A would be your other option. HI represents the length of the side opposite to ∠H while GI represents the length of the side adjacent to ∠H.
Hope that clears things up!
Answer:
2/23 or about 8.6%
Step-by-step explanation
Add the number of students
Basketball+baseball+neither
5+15+5=25
Subtract the number from the number of students in the class
25-23=2
This means that there are two students who play both.
Then phrase the number as a probability fraction.
2/23
