Assume that random guesses are made for seven 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 4.\[ P(X < 4) = \, \](Round to four decimal places as needed.)

Given data,n=7p=0.3P(X<4)=?P(X<4)=?=P(X=0)+P(X=1)+P(X=2)+P(X=3) P(X<4)=0.8740

The police tested 550 people, to see if anyone would match the partial fingerprint at the crime scene. The probability of getting a false-positive result for a single person, was 0.3%. In the video: What did we find was the approximate percentage probability, that out of 550 people tested, there would be at least one false-positive result? Round to four digits past the decimal point, and include a percentage symbol in your answer (with no spaces).
