Concept explainers
(a)
To explain how you would use each chance device to stimulate whether the light is red or green on a given day.
(a)
Explanation of Solution
To use each chance device to stimulate whether the light is red or green on a given day by a six sided die, we have,
Throw the six sided dice.
If the number of dots on the top side is
If the number of dots on the top side is
Thus, we know that, if the number of dots on the top side is
(b)
To explain how you would use each chance device to stimulate whether the light is red or green on a given day.
(b)
Explanation of Solution
To use each chance device to stimulate whether the light is red or green on a given day by Table D of random digits, we have,
Select a row from table D.
If the digit is a
If the digit is a
If the digit is zero, ignore the digit and move on to the next digit.
Thus, we know that, if the digit is a
(c)
To explain how you would use each chance device to simulate whether the light is red or green on a given day.
(c)
Explanation of Solution
To use each chance device to simulate whether the light is red or green on a given day by a standard deck of playing cards, we have,
Draw a card from a standard deck of cards.
In a deck of cards, you have an equal chance of selecting a suit (hearts, diamonds, spades or clubs)
If the card has the heart symbol, then she gets a green light.
If the card has a diamond or spade symbol, then she gets no green light.
If the card has a club symbol, then you need to draw another card.
Thus, we know that, if the card has the heart symbol, then she gets a green light.
