Ryan has 3 red lava lamps and 3 blue lava lamps. He arranges them in a row on a shelf randomly, then turns 3 random lamps on. What is the probability that the leftmost lamp on the shelf is red?
There are 3 red lamps to put as the first lamp.
There are 6 lamps to put as the first lamp.
So, tell me, what is the probability?
