Question

You roll a number cube. Event A: roll a number less than 3 Event B: roll a number greater than 3 Are the events disjointed or overlapping?

Answer 1

Disjointed I guess? Event A would would mean the numbers 1 and 2 while Event B would have the numbers 4,5,6. Event A doesn't share any numbers with B so it should be disjointed.

Answer 2

write the sample space first

Answer 3

sample space for A = {1,2}
but for B ={4,5,6}
now A intersection B = {} so disjoint...
