Problem

A simulation has already rolled two fair six-sided dice for you, once per trial. You are given the outcomes as a list rolls, where each element is a two-element list [die1, die2] and each die value is an integer from 1 to 6.

Write a Python function that returns the empirical probability that the sum of the two dice is 7: the fraction of rolls whose values sum to 7, returned as a floating-point number.

Constraints

1 <= len(rolls) <= 10^7
Each roll is a list [die1, die2] with 1 <= die1, die2 <= 6
The function returns a floating-point value in the range [0, 1]
