Answer: A. 5%
Step-by-step explanation:
Given : The chance that they will join the graduate program : p=0.10
The total number of students in the class: n = 400
For this binomial situation :
We assume that this is normal distribution.
Let X be the random variable that represents the students will be joining a graduate program.
Z-score :
For x= 50 , we have
Using the standard normal distribution table , we have
Hence, the value i.e.closest to the probability that at least 50 students will be joining a graduate program = 5%
Answer:
Step-by-step explanation:
From the given information:
Assuming we have an integer c to represent the components in the stocks.
Thus, the needed probability can be expressed as:
To break this down, we have:
By solving the equation:
n = 23
Thus, relating to the needed condition; n ≥ 23
The needed number of the components that should be in stock should be at least 23.
