We're currently studying the addition and multiplication rules in my statistics class (yaay.......) and today we came across this word problem in the textbook:

The Rock 'n' Roller Coaster at Disney-MGM Studios in Orlando has two seats in each of 12 rows. Riders are assigned to seats in the order that they arrive. If you ride this roller coaster once, what is the probability of getting the coveted first row? How many times must you ride in order to have at least a 95% chance of getting a first row seat at least once?

By the time the teacher finished reading the question I could hardly contain my laughter.

I raised my hand and gave my answer without doing the math:

I would only ride once and get in the separate line for the front row. Then I have a 100% chance of riding up front.

Apparently that's not the answer the author is looking for.

The correct answers were 1/12 and 35.:eek:

:veryconfu Always?? Well clearly it's NOT "always" a good thing. Sometimes insider knowledge can be a detriment, as evidenced by the OP's story....where insider knowledge kept him/her from getting the correct math answer.

mathematically it is possible for an elephant to sit on a leaf on a tree, biologically theres no way the elephant could get up a tree in the first place nor is their a leaf of sufficient dimensions that the maths indicate you would require.


Also the math doesn't account for the probability that the ride will beak down

This makes me think of numb3rs - 'we all use math everyday' - sorry, just such a lame opening line for such a great tv show.. i know it's off on a tangent....

I give you an A+. You got the correct answer. I would never wait in line 35 times to sit in the front. I just say "front please," then wait a couple extra minutes.

Guess its better than the one I found in my statistics book:

"A child gets lost in the Disneyland at the Epcot Center in Florida. The father of the child believes that the probability of his being lost in the east wing of the center is 0.75 and in the west wing is 0.25. The security department sends an office to the east and an officer to the west to look for the child. If the probability that a security officer who is looking in the correct wing finds the child is 0.4, find the probability the child is found."

You basically just described why there are mathematicians and engineers.

Man, I wished my engineering text books had problems like your stats book. That is hilarious. What a nice break from a myriad of numbers.:snore:

As someone who was "selected" at school to become a young engineer and forced to study engineering science and drawing all such numbers leave me cold.:shrug:

Thats said Im fairly handy when moneys involved :drevil:

I actually got the first row, by chance, my first time riding RNRC. They came through the line looking for a single rider. What are the chances of that? (Apparently 1/12!)
