A. In the push-pin throwing test, if the frequency of the nail tip facing upwards is 3/5, the probability of the nail tip facing upwards is 3/5.

Wrong, frequency is stable in probability, but it cannot be said that frequency is equal to probability;

B the median value of samples 0, 2, 5, 6 and 3 is 5.

The median is 3, not 5;

C. "If x>5, then x=6" is a random event.

D "The minimum value of (1+2x)- 1 under algebraic radical is-1" is an inevitable event.

Is it a multiple-choice question
