What are the odds against you choosing a person from the children or teen category? (children group has 3), (teen group has 2) (young adult group has 2) , (adult group has 5), (senior group has 3)

Question

Can you please show the steps? Thank you.

Answer 1

P(event) = total favorable outcomes/total possible outcomes

P(child or teen) = (total children + total teen)/total possible outcomes

P(child or teen) = (3+2)/(3+2+2+5+3)

P(child or teen) = 5/15 = 1/3
