    take all of you numbers on your wheel and add them up individually and put a 1 over that that would give you the probabiltity of spinning a 3 on a wheel. lets say you have numbers 1-5 and you want to know the chances of spinning a 3 since there are 5 numbers there is a 1/5 chance you will spin a 3

    Look at the figure above. Assuming each sector is the same size, then there are 8 sectors with equal likelihood of landing there. Two of the eight sectors are marked 3. P(3) = sectors with 3 / all sectors

    P(3) = sectors with 3 / all sectors = 2/8 Now you can reduce the fraction.
