Practice Binomial Distribution in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The probability distribution of the number of successes in n independent yes/no trials, each with probability p.
Flip a biased coin n times—how many heads? The binomial distribution gives the probability of each count.
Example 1
mediumA fair coin is flipped 8 times. What is the probability of getting exactly 5 heads?
Example 2
hardA multiple-choice quiz has 10 questions, each with 4 choices. If a student guesses randomly, what is the probability of getting at least 2 correct?
Example 3
mediumA basketball player has a 70\% free-throw success rate. In 6 attempts, what is the probability of making exactly 4?
Example 4
mediumA student guesses on 7 true-or-false questions. What is the probability of getting at least 6 correct?
