The total number of marbles in the bag is 1 + 4 + 3 = 8
The probability of drawing one marble and getting blue is 4/8 = 1/2
Since marble is put back and he draws again, the probability will again be 1/2
The total probability = 1/2 * 1/2 = 1/4.

The monthly failure rate is q = 5% = 0.05
The monthly pass rate is p = 1 - q = 0.95
We want to determine the probability of 12 passes in 12 consecutive months for a student.
P(12 of 12 successes) = ₁₂C₁₂ p¹² q⁰ = 0.95¹² = 0.5404.
Therefore if we have 100 students, the number that gets through 12 consecutive months is
100*005404 = 54 students.
Answer: 54 students are left after 12 months.
