So basically it's just a simple division equation (kind of):
600/3000
We can simplify this so the denominator is 100
20/100
So she saved 20% of her money in the month of January.<span />
The possible values of N from the given probability parameters is; N equals 15 or 21
<h3>How to Solve Algebra Problems?</h3>
We are told that;
Number of pens in the box = N
Let the number of red pens be x
Thus; number of black pens = x + 3
Thus;
x + x + 3 = N
x = (N - 3)/2
The probability that she will take a black pen followed by a red pen is;
P(she will take a black pen followed by a red pen) = (x + 3)/N * x/(N - 1)
Plugging in he relevant values and solving for N gives ;
Solving for N gives N equals 15 or 21
