The access code garage door consists of three digits. Eachdigit can be 0 through 9 and each digit can be repeated. hence total no. of digits = 10 since each digit can be repeated, (a) the number of possible access codes = 10 x 10 x 10 =1000 (b) the probability of randomly selecting the correct accesscode=?? there will be only one correct access code. hence probability = 1/1000 (c) the probability of not selecting the correct access code 1- 1/1000 = 999 / 1000Related Questions
