Question a four digit personal identification number (pin) is selected. what is the probability that there are no repeated digits? do not round

If a four digit personal identification number is selected, then the probability that there are no repeated digits is 0.504 Number of digits in the identification number = 4 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9 There are 10 digits The probability = Number of favorable outcomes / Total number of outcomes Total number of outcomes = 10 × 10 × 10 × 10 = 10000 Number of outcomes that digits wont repeat = 10 × 9 × 8 × 7 = 5040 Substitute the values in the equation of probability The probability = 5040 / 10000 = 0.504 Therefore, the probability there are no repeated digits is 0.504 Learn more about probability here brainly.com/question/11234923 #SPJ4 Log in to Reply
