Question

Assume that random guesses are made for multiple choice questions on an SAT​ test, so that there are n = 8 ​trials, each with probability of success​ (correct) given by p = 0.25. Find the indicated probability for the number of correct answers. Find the probability that the numbers of x of correct answers is fewer than 4.

Answer 1

Concept: Statistical Modeling

1. N= 8 trials
2. P= 0.25 or 1/4 chance
3. You have 8 * 1/4 = 2 correct
4. 
   `(p < .50) = (1)/(8)`
