Answer to Problem 106E
The probability that the slot player gets at least one apple in one pull of the lever is 0.67232.
Explanation of Solution
Given information:
The slot player gets at least one apple in one pull of the lever.
Formula used:
Calculation:
Obtain the probability that the slot player gets at least one apple in one pull of the lever:
It is given that, a slot machine has 5 wheels, and each wheel has 5 symbols (apple, grape, peach, pear and plum).
The wheel spins independently and the five symbols are equally likely to appear.
The probability that the slot player gets at least one apple in one pull of the lever is obtained as 0.67232 from the calculation given below:
Therefore, the probability that the slot player gets at least one apple in one pull of the lever is 0.67232.
Conclusion:
The probability that the slot player gets at least one apple in one pull of the lever is 0.67232.

Answer to Problem 106E
The probability that the slot player gets at least one apple in five pulls of the lever is 0.996222.
Explanation of Solution
Given information:
In the readers view, the lever was pulled 5 times.
Formula used:
Calculation:
Compute the answer for reader’s question:
In the readers view, the lever was pulled 5 times.
The readers question is to compute the probability of getting at least 1 one apple in five pulls of the lever.
The probability that the slot player gets at least one apple in five pulls of the lever is obtained as 0.996222 from the calculation given below:
Therefore, the probability that the slot player gets at least one apple in five pulls of the lever is 0.996222.
Conclusion:
The probability that the slot player gets at least one apple in five pulls of the lever is 0.996222.
