My son had 6 math questions on the bottom of his homework last night.
He got them all right.
I said, “great!”
He said he guessed on all of them!!
What are the odds that they’d all be right?
If there are 2 choices for each one, it is 1 in 64 (or 63-1 against).
No, itwas like 400-237 [equals is great than or lesser than] 255-133
If all six questions had three possible answers, then the odds are 729 to 1. (3^6 to 1)
Maybe your son was making (slightly) educated guesses, even if he believed they were completely random.
I’m glad he did well, but if he had to guess he probably needs to study more.
agreed.
or maybe he should start picking lottery numbers.
Lesse. . .
Assuming they weren’t multiple choice, the odds of picking the right numerical answer out of the aether is infinity to one against.
So, the odds are
(1 )^6
( - )
( infinity )
Or 0. I say he read the back of the book.
Apparently they were multiple guess.
It was a page of homework, there was no back-of-the-book.
He was a good guesser!
