<u>Answer: </u>
The probability of rolling a number greater than 4 or less than 3 is
<u>Solution: </u>
In the given question there are two events as follows:
(a) Rolling a number greater than 4 i.e. A = {5,6}
(b) Rolling a number less than 3 i.e. B = {1,2}
Since a die has 6 numbers,
P(A) = where P(A) is the probability of occurrence of event A and P(B) =
Since, Event A and Event B has nothing in common therefore they are mutually exclusive events.
P(A∪B) = P(A) + P(B)
Therefore the probability of getting a number greater than 4 or less than 3 is
Answer:
The sample required is
Step-by-step explanation:
From the question we are told that
The standard deviation is
The margin of error is
Given that the confidence level is 99% then the level of significance is mathematically evaluated as
Next we will obtain the critical value from the normal distribution table(reference math dot armstrong dot edu) , the value is
The sample size is mathematically represented as
substituting values
