Assume that random guesses are made for multiple choice questions on an SAT​ test, so that there are n=7 ​trials, each with probability of success​ (correct) given by p=0.3. Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is fewer than .

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

step-by-step explanation:
