a) A group of girls at a school are entered for Advanced Level mathematics models. Each girl takes only module Mor module M2 or both M and M2. The probability that a girl is taking M2 given that she is taking M, is 1/5. The probability that a girl is taking M1 given that she is taking M2 is 1/3. Find the probability that 2 20. 20 i. A girl selected at random is taking both M, and M2 (4marks) 3 ii. A girl selected at random is taking only M2 (2marks)​

Write the pseudocode for the following: a function called fahrenheittocelsius that accepts a real fahrenheit temperature, performs the conversion, and returns the real celsius temperature. a function called celsiustofahrenheit that accepts a real celsius temperature, performs the conversion, and returns the real fahrenheit temperature. a main module that asks user to enter a fahrenheit temperature, calls the fahrenheittocelsius function, and displays the celsius temperature with a user-friendly message. it then asks the user to enter a celsius temperature, calls the celsiustofahrenheit function, and displays the fahrenheit temperature with a user-friendly message.

Dean wants a quick way to look up staff members by their staff id. in cell q3, nest the existing vlookup function in an iferror function. if the vlookup function returns an error result, the text “invalid staff id” should be displayed by the formula. (hint: you can test that this formula is working by changing the value in cell q2 to 0, but remember to set the value of cell q2 back to 1036 when the testing is complete.)
