A roulette wheel has $36$slots around the rim. The first $32$slots are numbered from $1$ to $32.$ Half of these $32$ slots are green and the other half are yellow. The remaining $4$slots have jackpot, bumper, try again and penalty inscribed on them. A small ivory ball spun in the direction opposite to that of the wheel has equal chances of falling in any one of the $36$ slots. Find the probability that the ball lands in a yellow slot.
