    • Representing the three letters with A and the four digits with 1, some of the possible permutations are as follows:
      AAA1111
      AA1A111
      AA11A11
      A1AA111
      A1A1A11 There are 7!/(4!*3!) possible permutations in total. Each letter has 26 possibilities and each digit has 9 possibilities. (as 0 is not an option)
      This gives us 26^3 ways of choosing the three letters and 9^4 ways of choosing the four digits. (Order matters here: AAB ≠ ABA) Now we simply multiply the three results.
      That is,
      (26^3)*(9^4)*(7!/(4!*3!))
      =17576*6561*35
      =4,036,064,760 That easy.
    • Student passwords consist of three letters chosen from A to Z, followed by four digits chosen from 1–9. Repeated characters are allowed. How many possible passwords are there? [4 marks]

    • So this is my IA question "The relationship between countries’ GDP and the life expectancy of its population", what should I look at? My plan of investigation is: I am going to make a scatter plot and make of a line of best fit to see if there is a linear correlation between the data collected. After that, I will find the standard deviation in order to find out the dispersion of the data. With the data found, I will find the least-squares regression line to find out the equation of the line. After I will use Pearson’s Correlation Coefficient to find out the strength of the linear relationship between two variables.  To finalize my investigation I will look at the Chi-squared test to see if the data used is dependent or independent.  Should I look at anything else? Should I change anything from my plans?   Thanks.
