Random number generation in a programming language Questions

Practise AQA GCSE Computer Science Random number generation in a programming language with exam-style questions for GCSE Computer Science. 8 questions, matched to the AQA GCSE Computer Science (8525) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.

Write the VB.NET code that should be used on line 3 of the program below to:

generate a random integer between 1 and 50 inclusive
assign this number to the appropriate variable from the program.

You must use rand.Next(a, b) in your VB.NET code.

Note: rand.Next(a, b) generates a random integer starting at a up to, but not including, b.
