A sample of a radioactive isotope had an initial mass of 330 mg in the year 1990 and decays exponentially over time. A measurement in the year 1995 found that the sample's mass had decayed to 160 mg. What would be the expected mass of the sample in the year 2003, to the nearest whole number?

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
