The Last Cookie Riddle
Mike and James are arguing over who gets the last cookie in the jar, so their dad decides to create a game to settle their dispute. First, Mike flips a coin twice, and each time James calls heads or tails in the air. If James gets both calls right, he gets the last cookie. If not, Mike picks a number between one and six and then rolls a die. If he gets the number right, he gets the last cookie. If not, James picks two numbers between one and five, then spins a spinner with numbers one through five on it. If the spinner lands on one of James' two numbers, he gets the last cookie. If not, Mike does.
Who is more likely to win the last cookie, Mike or James? And what is the probability that person wins it?
Who is more likely to win the last cookie, Mike or James? And what is the probability that person wins it?
Hint: Their dad is a very smart person.
Believe it or not, both Mike and James have a 1/2 chance of winning.
James wins if:
-he calls both coin flips right = 1/2 x 1/2 = 1/4
OR
-he does not call both coin flips right, Mike does not call the die roll correctly, and he guesses the number on the spinner right = 3/4 x 5/6 x 2/5 = 30/120 = 1/4
1/4 + 1/4 = 1/2
Mike wins if:
-James does not call both coin flips right and he calls the die roll correctly = 3/4 x 1/6 = 3/24 = 1/8
OR
-James does not call both coin flips right, he does not call the die roll correctly, and Mike does not guess the number on the spinner right = 3/4 x 5/6 x 3/5 = 45/120 = 3/8
1/8 + 3/8 = 1/2

McDonalds Riddle
A brainteaser involving what looks like some simple math with McDonald's burgers and fries has left people starving for the correct answer. Can you solve this McDonalds riddle?
Hint: The key is to first determine how much each item is worth. The drink is clearly worth 10, and it's apparent from the second line that the burgers are worth five.
Pictures of the fries are each worth two, but you have to keep in mind that each individual packet of fries is worth one when you get to the next line. That has baited people into thinking, incorrectly, that the last line is 5 + 2 x 10.
The fourth line has also thrown many people off because it involves order of operations after already including the tricky single packet of fries.
Multiplication comes before addition, so you have to multiply one packet of fries by one drink and then add that to one burger. Thus, 5 + (1x10) = 15. Did you answer this riddle correctly?
YES NO
