On each turn, I roll a standard six-sided die.
If the number that is rolled is less than or equal to the number (i.e. between \(1\) and \(5\) inclusive) of the square which the counter is on, I move the counter to the left one square. Otherwise, I move the counter to the right one square.
If I move the counter onto the green square, which is shown in the picture, I win.
However, if I move the counter onto the red square, I lose.
If the probability that I win the game is represented by \(\frac{A}{B},\) for positive coprime integers \(A\) and \(B,\) what is the value of \(B - A?\)
