Yanay gets a lot of spam calls. An area code is defined to be a three digit number from 200-999 inclusive. In reality, many of these area codes are not in use, but for this question we'll simplify things and assume they all are. Throughout these questions, you should assume that Yanay's area code is 781. In [ ]: Question 1. Assuming each area code is just as likely as any other, what's the probability that the area code of two back to back spam calls are 781? In [ ] #Write your answer below. prob_781 = prob_781 Question 2. Rohan already knows that Yanay's area code is 781. Rohan randomly guesses the last 7 digits (0-9 inclusive) of his phone number. What's the probability that Rohan correctly guesses Yanay's number, assuming he's equally likely to choose any digit? Note: A phone number contains an area code and 7 additional digits, i.e. xxx-XXX-XXXX prob_yanay_num prob_yanay_num Yanay gets a lot of spam calls.
