刚面完, 问题如下
1. A bag contains 40 balls, each of which is black or gold. A person reaches
into the bag and randomly removes two balls. Each ball in the bag is
equally likely to be removed. If the probability that two gold balls are
removed is 5/12, how many of the 40 balls are gold?
2. Player A and Player B will play 6 games of table tennis. Each is equally
likely to win any given game.
The probability that each of them will win 3 games out of 6 is 5/16.
What is the probability that Player A will win more games than player B?
3. sentence fragments english words, 7 - 12 words long, build features and
model to determine if the sentence has significant meaning?
examples:
i am a goat / high significance
game no note have / median significance
the the the the / low significance
