Probability Help Needed: Tertiary Education in African Countries

[DAMES]

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.
