a.
Answer to Problem 6CRE
The probability is 0.1678.
Explanation of Solution
Given:
Probability of success ( p ) = 20% = 0.20.
Number of trials ( n ) = 8
Calculation:
Here, X is a random variable that shows the number of orange candies.
The probability of selecting 0 orange candies is:
Thus, the probability is 0.1678.
Here, probability is above 5%. Thus, the
b.
To explain: Whether it could make you surprise if more than 5 orange candies are selected. Also, compute the probability to support the answer.
b.
Answer to Problem 6CRE
The probability is 0.0104.
Explanation of Solution
Calculation:
The probability of selecting more than 5 orange candies is calculated as:
Thus, the probability is 0.0104.
Here, probability is below 5%. Thus, the event is surprising to happen.
