So the car starts on the circumference? Good
So find the circumference first, we needa use that to determine how far along the thing he went.
21.5*2pi = 135.0884841043611093
I'm not gonna round till the end
12 rounds per minute, and a 6 second ride.
The ride makes a round every 5 seconds, so we needa add one round plus 1/5th a round to get
135.088 + 135.088(1/5) = 162.10618092523333116 - I shortened the equations after the calculation, so it wouldn't take up so much space. The calculations are completely accurate
So, he rode around for 162.10618092523333116 feet
Nevermind, I'm stupid. Just take 1/5th the round and then move him that far along the circumference to find the coordinates.
135.0884841043611093(1/5) = 27.01769682087222186
Now here is where I need CPhill.... I don't have any clue as to how to calculate coordinates on a circle.
Part A: 4 7's ina deck of 52 right?
So it's 4/52 if a 7 gets drawn?
4/52 = 2/26 = 1/13
So it's a 1 in 13 chance of a 7 getting drawn
Do that twice
Part B: First draw, it's a one in 4 chance of getting a heart, due to 13 cards of each suite in a 52 card deck.
But then it is a 13 in 51 chance for the heart, due to the non-replacement
13/51 * 1/4 = 13/204 chance of getting that combination
Part C: B is a dependent even due to the cards being drawn depending on the cards previously drawn. If you draw a Spade, then instead of a 13/52 chance, you have a 12/51 chance of drawing another spade. And etc. till you get to a 1/40 chance of getting a spade, if you, somehow, get 11 consecutive spades.
