back to boardHow you think, from what attempt it is possible to get AC? How you think, from what attempt it is possible to get AC? cout<<rand()%10; Re: How you think, from what attempt it is possible to get AC? Seems that probability of AC is (1/10) ^ k where k is number of tests. So probability to get just one AC after N attempts is 1 - ( 1 - (1/10) ^ k ) ^ N ^_^ Good luck. ;) P.S.: if k = 10, you have to make 6931471806 attempts for making this probability greater then 0.5 xD P.P.S: ...if i made no mistakes. ;) |
