To solve this we are going to use the formula fro the force applied to a spring: 
where
is the spring constant
is the extension
Since we know the
, we can replace that in our formula and solve for 
:
where
is the acceleration
is the spring constant
is the extension
is the mass
We know for our problem that
,

Answer:
There is a 45.05% probability that the selected person is a right-handed female.
Step-by-step explanation:
We have these following probabilities
A 50% probability that a person is a male
A 50% probability that a person is a female.
A 12.6% probability that a male is left-handed.
A 9.9% probability that a female is left-handed.
If a person is selected at random, to find the probability that the selected person is a right-handed female, one would compute:
50% are female.
9.9% of the females are left-handed, so 100-9.9 = 90.1% of the females are right handed.
So
There is a 45.05% probability that the selected person is a right-handed female.
