I just need to know how to find no solution, infinite, two, and one solution that’s all I need not the answer I want to figure that out on my own. Thank you!

My math teacher told my class to "steal" a 6th grade fraction word problem from the internet, word problems? : -p requirements: only a 1 step word problem. needs to be complex.

Given: pqrs is a parallelogram prove: pr and qs bisect each other at t

Events a and b are independent. the probability of a occurring is 2/5. the probability of b occurring is 1/4. what is p(a and b)?
