Will this girl say yes or no to a date?

In the past i've had bad luck with girls. But i feel like with every girl that I've tried to go out with a date that i've improved a little. But this girl i met in my class around early October and we started to talk because of a an assignment she had a question on. I added her on fb and over the next week or so she started to im me about school work and questions and stuff. After her questions i steered the convo for more personal stuff and we've talked here and there. Then in class after it ends we walk to our cars together and things and she waits for me. Next about 2 weeks ago i'll say mid way through October we had a 5 hour convo online about everything. She imed me about school and then we started to talk about tv shows and we joke around with each other. She laughs at my jokes through texts and things. So i took this as a good sign so I asked her if she wanted to go to a basketball game with me because I had 4 tickets and I said that she could invite a friend. At first she said that was the night she was going bar hopping with her friends because it was her birthday. However, the next day she told me that she was able to change the plans and she'll go out with her friends another weekend to celebrate her birthday. Now i'm not sure if she lied before or she actually changed her plans but she went. I met her friend and we had a good time. Now i've been trying to step it up a little. I've text her good luck in the morning and good luck at work. And just recently i sent her a funny article about her favorite sport and she said that was really funny. I want to ask her out on tuesday? Will she say yes or is she just being nice because were in the same class?
