陈老师最近事情比较多。这天,她要在发给同学们的奖品和奖状上写上名字,但是在忙乱之中写错了。她把一些人的名字和对应的奖项写错了,而且每个奖项下面只可能有一个名字,所以即使出错,也只可能是以下3种情况:1正好有3个人写对了;2正好有2个人写对了;3正好有1个人写错了。请你帮助陈老师算一算,她总共写错了几个人的名字? Chen more things recently. On that day, she wrote her name on the prizes and certificates she gave to her classmates, but she made the mistake during the fuss. She misprestered some people’s names and corresponding prizes, and each prize could have only one name below, so even if something went wrong, it could only be one of three things: 1 There were exactly 3 people writing right; 2 There were exactly 2 people wrote right; 3 exactly one person is wrong. Please help Chen calculate the sum, she wrote a total of a few wrong people’s name?
