I want to know the answer to the following question:
How many awards did Beyoncé win at the 57th Annual Grammys?
All the background I'm provided with is that "At the 57th Annual Grammy Awards in February 2015, Beyoncé was nominated for six awards, ultimately winning three: Best R&B Performance and Best R&B Song for "Drunk in Love", and Best Surround Sound Album for Beyoncé.". Is that enough to answer the question?
Answer: yes
