In an extrasensoryperception experiment, a blindfolded subject has two rows of blocks before him. Each row has blocks numbered 1 to 10 arranged in random order. The subject is to place one hand on a block in the first row and then try to place his other hand on the block having the same numerical in the second row. If the subject has no ESP, what is the probability of his making a match on the first try?

I am thinking it should be 1/100, multiplying by the 1/10 x 1/10 (the probability of the identical numbers in each row)
