The casino game, roulette, allows the gambler to bet on the probability of a ball, which spins in the roulette wheel, landing on a particular color, number, or range of numbers. The table used to place bets contains of $38$numbers, and each number is assigned to a color and a range.

Total number $=38$

In two lines, there are $6$numbers

Thus, we need to find the probability of winning by betting on two lines that touch each other on the table.

Require probability is
