Show step by step work. Give answer in fraction in lowest terms.
-------------------------------
On Tuesday the nurse spent 3 hrs. + 1 hr assisting an MD
She spent 4/24 hrs. on those activities.
---
On Wednesday the probability the nurse will be involved in one of those
activities at any given moment is 1/6. The probability she will not
be involved in that way is 5/6.
The odds infavor of her being involved as described is 1:5
----
Comment: The words "what are the chances" makes the problem ambiguous.
Do they want probabilities or do they want odds?
