Probability Help Needed: Tertiary Education in African Countries

Click For Summary
SUMMARY

The discussion centers on calculating the probability of more than 8 out of 10 randomly selected individuals aged 18 to 30 in African countries having tertiary education. Based on research, 66.67% of this demographic holds either a matric certificate or no formal education. To solve the problem, understanding the Binomial Distribution is essential, as it provides the framework for calculating probabilities in scenarios with fixed trials and two possible outcomes.

PREREQUISITES
  • Understanding of Binomial Distribution
  • Basic knowledge of probability theory
  • Familiarity with statistical sampling methods
  • Ability to perform calculations involving combinations
NEXT STEPS
  • Study the principles of Binomial Distribution in detail
  • Learn how to calculate probabilities using the Binomial formula
  • Explore statistical sampling techniques relevant to demographic studies
  • Practice problems involving probability calculations for real-world scenarios
USEFUL FOR

This discussion is beneficial for students studying statistics, educators teaching probability concepts, and researchers analyzing educational demographics in African countries.

Hello :) my question is on Probability.

"Based on the research done in African countries, 66.67% of the sample taken of the average skills level of people between the age of 16 and 30 is a matric certificate or no formal education.
Q:Assume that you randomly email 10 people between the ages 18 to 30 years; calculate the probability that more than 8 people have some form of tertiary education."

I am completely lost and really in need of someone to help me with this.
Thank you so much.

Hi DAMES,

Welcome to MHB! :)

Are you taking a class on probability or basic statistics? Have you discussed a distribution called the Binomial Distribution? The way to answer this question depends on some assumptions we make about this situation.
 
Hey, thanks for replying to me! I am doing the course part time so I am unable to go to lectures so no i have not covered that yet. View attachment 5351

Ive attached other info relevant to this question...
Could you please assist?
