The complementary event of that the last four digits include at least one 0 is that the last four digits do not include any 0. So, for the first digit, there are 9 ways to pick a digit from 1 to 9. Similarly, there are 9 ways to pick each of other digits. Then the probability that a 4-digit numbers that do not include 0 is chosen is (9*9*9*9)/10^4 = 0.6561. So the probability that the last four digits include at least one 0 is 1 – 0.6561 = 0.3439
First, the formula for the average of a data set must be defined. It is calculated by adding all the numbers in the data set and then dividing the sum by the number of data. In this case, the average is set to be equal to $400 with the total number of data being 3, with the September expenditure set as an unknown, x. The equation is then set-up to be: 400 = (401.5 + 250 + x)/3. Thus, Joshua can spend as much as $ 548.5 to be able to have the same average as in his second quarter expenditure.
