For #5 would the probability formula be
P(A) = number of favorable events/number of total eventsE7B8EAB8-91BB-4DE1-862D-188AA5E9A364.png
 
10 = total number of letters
4 = total number of vowels
P(selected letter is a vowel) = number of vowels/number of letters
P(selected letter is a vowel) = 4/10 = ⅖

P(selected letter is not a vowel) = number of non-vowels/number of letters
P(selected letter is not a vowel = 6/10 = ⅗

Is this correct?

Ive shortened it.
P(A) = number of favorable events/number of total events
10 = total number of letters
4 = total number of vowels, and 6 = total number of non-vowels

P(selected letter is not a vowel) = number of non-vowels/number of letters
P(selected letter is not a vowel) = 6/10 = ⅗
