The probability that a spin of the spinner will land on an upper case letter or a consonant can be calculated by adding the probabilities of the two events.
There are 26 upper case letters in the English alphabet and 21 consonants (excluding Y) in the English alphabet. There are 26 + 21 = 47 total possible outcomes.
The probability of landing on an upper case letter is 26/47 and the probability of landing on a consonant is 21/47.
Therefore, the probability of landing on an upper case letter or a consonant is 26/47 + 21/47 = 47/47 = 1.
Therefore, the answer is 1.
