Answer:
Step-by-step explanation:
The formula for this is
where
N is the amount of the element left after a certain amount of time (for us it is measured in days),
N₀ is the initial amount of the element in grams,
t is the number of days gone by, and
H is the half life of the element. Filling in:
which simplifies a bit to
and a bit more to
N = 42(.25) which gives us a remaining amount of
N = 10.5

Step-by-step explanation:
There are three different options to pick in the bag, so the probability of getting a nickel first is 1/3, and then the probability of getting a penny without replacing the nickel is 1/2, as there will be only 2 options remaining after the nickel was picked.
So the final probability is the product of these probabilities:
P = (1/3) * (1/2) = 1/6 = 0.166 = 16%
