Coincidence…?

Today in my Swedish class we were learning different verbs. The prof. was putting pictures up of people doing things like reading, writing, talking on the phone, watching TV, etc. and she would tell us what they were doing. There were about 20 pictures and one of the pictures had a guy playing the guitar.

Vad gör han? (What is he doing?)
Han spelar gitarr. (He plays the guitar.)

We also learned how to say “every day, week, month, etc.” (varje dag, vecka, månad, etc.). The teacher was then selecting random students to ask another if he/she did an activity (and how frequently). I thought to myself: “It would be cool if the picture of the guitar guy [randomly] goes up and she [randomly] asks someone to [randomly] ask me since I DO play the guitar!”. However, all the students asking the questions were asking: “Do you do xxx every day?” Since I don’t play the guitar everyday I would have to say “No.” and no one would know I played the guitar even if I was randomly selected.

Finally, the pic of the guitar went up. She selected a guy and then told the guy to ask me! He was the first person to change the sentence from “every day to “every week!

“Spelar du gitarr varje vecka?” (Do you play the guitar every week?)
“Ja, jag spelar gitarr varje vecka!” (Yes, I play the guitar every week!)

What were the odds of that happening? Can anyone remember their statistics class? The odds of the guitar pic going up were 1/20, the odds of selecting a student OTHER than me were 29/30, the odds of selecting me were 1/29 and finally the odds of the guy saying “week” were 1/4. I can’t remember how you combine all those probabilities. Is it exponential if the events are mutually exclusive? I don’t remember. Whatever.

Was it coincidence? Or did it happen because I was really thinking about/imagining it? Consider that…
