In regards to intersections, how would I add the events A (2, 3, 4, 5) and B (2, 3, 6, 7)?
I know that A *inverted u like an umbrella* B will be (2, 3) because A and B both have these numbers in common
What, then, happens to the rest? like A (4, 5) and B (6, 7) ?
Please express to me how to write this and also the difference between the *u* between two letters or the *inverted u*
