You stated that Mark 16:10-11 contradict that the women didn't tell anyone else. However, in the NIV, it states: "The most reliable early manuscripts and other ancient witnesses do not have Mark 16:9-20." Many biblical scholars believe that 16:9-20 were added much later and as such are not accurate; at any rate, there is enough doubt about the accuracy of verses 10 and 11 that a contradiction is still likely to exist.
