A roulette wheel is constructed so that the numbers can fall from 1 to 10 and the probability of falling a number (k + 1) is 2 t
imes greater than the number k (for k = 1; 2; 3; ... 9). Find the probability that:
a) drop number 1; b) drop number 10.
End as a decimal number rounded to 3
digits after the decimal point.
(i know the answer a is 0.001 and b is 0.500
but i don't know how to solve it)
