class lunch

my class's having a lunch outing today at 12pm at tm. audrey says that we're probably gonna eat seoul garden, but i'm weighing the cost(of being scolded by my mum for spending 1680 on carls jr and 790 on coffee) and benefit.(able to spend time with my classmates)

hahha. also, i've just recieved a message from a unknown person, writing "Heys, its yunus here. nice meeting yah jus now =) take care..." in the exact same words. i guess there are people who do give fake numbers to avoid being contacted. but upon further thinking, since the number of ways i can permutate a handphone number is {|9|9|9|9|9|9|9|9| minus |1(9)|1(9)|2(5,9)|9|9|9|9|9| - |1(9)|1(1)|1(1)|9|9|9|9|9| minus 1(the person's number itself)} which is equals to {43046721 - 118098 - 59049-1} which is equals to {42869573}. this means that the probability of a person writing my number when permutating a random number is 2.332656777 x 10^-8. wow. is that as lucky as striking lottery? maybe i'll try tomorrow. meanwhile, if i do my calculation wrongly, feel free to correct me.

i'm going to sleep alr!
