Answer:
Step-by-step explanation:
<u>Let's simplify the problem.</u>
Hence, the solution to the problem is 625/4096.
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.
Rationalize the denominator, divide by 4, add 2.
I think it's a acute but I'm not sure
