# Waiting for first coin flip

You'll start by simulating a series of coin flips, and "waiting" for the first heads.

Instructions

**100 XP**

- Simulate 100 instances of flipping a single coin with a 20% chance of heads, and save it as the variable
`flips`

. (Thus,`flips`

should be a vector of length 100). - Use
`which()`

to find the first case where a coin resulted in heads.
