Answer:
The probability of picking a non-vowel = 9/10
Step-by-step explanation:
Each letter has an equal probability of being picked.
Vowels; e
Number of vowels =1
Non-vowels; b,c,d,f,g,h,l,j,k
Number of non-vowels= 9
Probability of picking a non-vowel = 9/(1+9) = 9/10
I think the answer is -1.1428
