1) The game Mastermind consists of one player creating a hidden code and the other player attempting to guess the code. A code consists of a sequence of four round pegs and each peg can be one of six different colors (red, orange, yellow, green, blue, purple). For example, the player making the code might choose "Blue, Purple, Green, Blue" (colors can repeat). When guessing, the colors and the sequence must match, meaning the guess "Purple, Blue, Blue, Green" would be incorrect. a) How many different codes can be formed? b) How many codes contain four different colors? c) What is the probability that a random code contains no red pegs? d) What is the probability that a random code contains exactly three pegs of the same color?

I need help answering the questions in this image!

1) The game Mastermind consists of one player creating a hidden code and the other
player attempting to guess the code. A code consists of a sequence of four round pegs
and each peg can be one of six different colors (red, orange, yellow, green, blue,
of 2
purple).
For example, the player making the code might choose "Blue, Purple, Green, Blue"
(colors can repeat). When guessing, the colors and the sequence must match, meaning
the guess "Purple, Blue, Blue, Green" would be incorrect.
a) How many different codes can be formed?
b) How many codes contain four different colors?
c) What is the probability that a random code contains no red pegs?
d) What is the probability that a random code contains exactly three pegs of the same
color?
2) A bag contains 14 poker chips: 2 Red, 5 Yellow, 3 Blue, 4 Green
A group of three chips are randomly drawn from the bag.
a) How many different groups of 3 chips can be drawn?
b) What is the probability that both red chips are drawn?
c) What is the probability that all three chips are the same color?
d) Given that all three chips are the same color, what is the probability that they are all
yellow?
