If all possible results are equally likely, what is the probability that a spin of the spinner will land on an upper case letter or a consonant? (1 point) Responses 0.9 0.9 0.7 0.7 0.5 0.5 0.3 0.3
The probability of landing on an upper case letter is 21/26 because there are 21 upper case letters out of a total of 26 letters in the English alphabet.
The probability of landing on a consonant is 21/26 as well because there are 21 consonants out of a total of 26 letters in the English alphabet.
Since the question asks for the probability of landing on either an upper case letter or a consonant, we can add the probabilities of landing on an upper case letter and landing on a consonant:
21/26 + 21/26 = 42/26 = 0.8077
Therefore, the probability that a spin of the spinner will land on an upper case letter or a consonant is approximately 0.8.
