Answer:
Binomial Problem with n = 20 and p(hire woman) = 1/2
P(at most two) = binomial(20,1/2,2) = 0.0001811
Step-by-step explanation:
The probability of successes in trials where is the probability of success on any given trial is given by:
1 hit in 5 times a bat
1/4 = .25
2/3 = .66
1/5 = .20
.25 + .66 + .20 = 1.16
1.16/3 = .38
This is closer than you would if you hit 2 hits in 4 times
The way to solve the question is by dividing 2 and 32 = 16
It can’t really see the question at this angle :/
Answer:
The proportion of individuals score at most 74 points on this test is 70%.
Step-by-step explanation:
The complete question is:
Suppose that the scores on a reading ability test are normally distributed with a mean of 70 and a standard deviation of 8. What proportion of individuals score at most 74 points on this test? Round your answer to at least four decimal places.
Solution:
Let <em>X</em> represent the scores on a reading ability test.
It is provided that .
Compute the probability that an individuals score is at most 74 points on this test as follows:
Thus, the proportion of individuals score at most 74 points on this test is 70%.
