#Probability wording which changes the meaning of the question. Pretty basic but I want an answer.

hullo!
i just got the result for my grade 10 final paper and there was a really poorly worded probability question that I lost marks on-
Each of the letter of the word 'SECONDARY' is written on identical circular disc and put in a bag. They are well shuffled. If a dice is thrown at random from the bag, what is the probability that the letter is one of the first eight letters of English alphabet which appears on the given word?
ok, now my teacher says that we take the first 8 letter of the alphabet and see how many letters coincide
BUT if you think about it, it says that the letter is one of the first 8 to appear in the word, not in the alphabet. If we use my teacher's arguement, the 'which appears on the given word?' part is completely redundant. I think the answer should be 8/9. What do you think?

i think you're both wrong?

#

it's 5/9, the letters a b c d e

#

oh that's what your teacher did

#

yeah, you're both right rather

#

the last part is redundant, but it's obviously 5/9

#

yeah your answer makes sense too
