Calculate Probability of Heads and Red Balls Drawing
Problem Description
This exercise presents two independent probability questions, requiring the application of fundamental statistical rules such as binomial distribution for independent trials and hypergeometric distribution for sampling without replacement.
Questions
- You flip a fair coin three times. What is the probability of getting exactly two heads?
- A bag contains 4 red and 6 blue balls (10 total). You draw two balls without replacement. What is the probability that both are red?
