Spreadsheet+CountIF

The CountIF function counts the number of cells in a range, that meets a given criteria.

Task
The Brit Awards 2011 have produced a spreadsheet which contains the following data:
 * whether the nominated artist is solo or group
 * how many weeks each nominated single spent in the Top Ten

The organising committee also want to use the spreadsheet to count:
 * the number of solo artists nominated for the Best UK Single award
 * the number of groups nominated for the Best UK Single award
 * how many singles were in the Top Ten for more than 5 weeks

Copy the spreadsheet below, and make sure that the cells B16, B17 and B19 use a COUNTIF function
