sorry no hate but surely the lower bound in the very first quesion would be 55 becuase the ineqaulity is not higher or equal o 54 but higher than 54, therfore the lower bound would be 55 right?

Thanks for making
these videos it helps me so much

Why is the LB 54 and not 55 when the question says the score has to be higher than 54 in part a).

[moarming]

Isnt the lower bound 55? because it says HIGHER than 54 so 55 and above right?

[sebimoggi]

If you want a score higher than 54 would the lower bound be 55 not 54 because its not including 54 its anything higher than 54
