(a).
To calculate: The probability that it will end up with no red ones.
The probability that you will end up with no red ones is
Given information:
A vending machine contains
Calculation:
A vending machine have 12 red gumballs, 5 white, and 3 blue ones. And it will put 3 coins in to get 3 different gumballs, and it does not want any red ones at all.
Since it is getting 3 different gumballs each time there will be one less.
Multiply them together to get the probability of not getting any red gumballs:
Hence, probability that you will end up with no red ones is
(b).
To calculate: The probability that it will
The probability that it will
Given information:
A vending machine contains
Calculation:
A vending machine have 12 red gumballs, 5 white, and 3 blue ones. And it will put 3 coins in to get 3 different gumballs, and it does not want any red ones at all.
First, choose from
Now, choose from
Choose from
Now, add them
Hence, the probability that it will
(c).
To calculate: The probability that a set of red, white, and blue.
The probability that a set of red, white, and blue is
Given information:
A vending machine contains
Calculation:
A vending machine have 12 red gumballs, 5 white, and 3 blue ones. And it will put 3 coins in to get 3 different gumballs, and it does not want any red ones at all.
Since each time you take a gumball out of the machine the total number goes down. Multiply the numbers together and get
Hence, probability that a set of red, white, and blue is
