某厂家为调查一种新推出的产品的颜色接受程度是否与性别有关，数据如下表：
黑红
男179
女622
根据表中的数据，得到k=
54×(17×22-9×6)2
26×23×31×28
≈10.653，因为K2≥7.879，所以产品的颜色接受程度与性别有关系，那么这种判断出错的可能性为______．
答案

提出假设H0：产品的颜色接受程度与性别没有关系

根据表中的数据，得到 k=

54×(17×22-9×6)2
26×23×31×28
≈10.653

对照临界值表可以得到P（K2≥7.879）=0.005

∵题中K2≈10.653≥7.879，

∴当H0成立时，K2≥7.879的概率约为0.005，

因此我们有99.5%的把握认为产品的颜色接受程度与性别有关系

这种判断出错的可能性是0.005

故答案为：0.005
