In the futuristic state of Xylos, license plates are composed of three symbols. The first symbol must be a prime digit (2, 3, 5, 7), the second must be one of the first 10 consonants (B, C, D, F, G, H, J, K, L, M), and the third must be a vowel that is not 'A'. If the symbols are chosen at random subject to these conditions, what is the probability that the plate will read "7LI"?
