Question

If a student estimated that the probability of correctly answering each question in a​ multiple-choice question is

60​%, use the binomial tables to determine the probability of earning at least a 70​% grade on a 20​-question exam.
**Probability in Multiple-Choice Exams**

In the given scenario, a student estimates the probability of correctly answering each question in a multiple-choice exam as 60%. Using binomial probability tables, the task is to determine the probability of earning at least a 70% grade on a 20-question exam.

To explore this, you can access the binomial probability tables by clicking on the provided icon.

**Question to Consider:**
- What is the probability of earning at least a 70% grade? 
  (Please round your answer to four decimal places as needed.) 

This problem involves understanding and applying concepts of binomial probability, which is crucial in statistical analysis for predicting outcomes in situations where there are fixed numbers of trials with two possible outcomes.
