How much of a radioactive kind of calcium will be left after 10 days if the half-life is 5 days
and you start with 64 grams?
me !

16 g

Step-by-step explanation:

We can solve this with the Radioactive Half Life Formula:

Where:

is the final amount of radioactive calcium

is the initial amount of radioactive calcium

is the time elapsed

is the half life of radioactive calcium

Solving with the given data:

 This is the amount of radioactive calcium left

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 %
