Determine the probability that few than 7 boxes will be needed.
This is represented as:

And the solution is:

Each probability is calculated by dividing the number of dots by the total dots.
So, we have:

From the attached, the formula becomes:



Is that suppose to be the problem?
Answer:
This is an equation of tangent and normal to the curve
Answer:
a^2 + 2a + 2
Step-by-step explanation:
replace x with (a +1) everywhere in the equation
f(a+1) = (a+1)^2 + 1
➡
a^2 + 2a + 1 + 1
