Question

You're playing a game where you defend your village from an orc invasion. There are 3 characters (elf, hobbit, or human) and 5 defense tools (magic, sword, shield, slingshot, or umbrella) to pick from. If you randomly choose your character and tool, what is the probability that you wont be a hobbit or use an umbrella

Answer 1

The probability that you won't be a hobbit=

`(2)/(3)`

The probability that you won't choose an umbrella=

`(4)/(5)`

Explanation:

The characters are 3, minus the hobbit gives you 2. So the probability of that=

`(2)/(3)`

The weapons are 5, minus the umbrella is 4. So the probability of that=

`(4)/(5)`
