@NerddSwaqqq1226 Can 13 be factored?

anonymous · Answer

I. Have. No. Clue. lol

ash2326 · Answer

You know what's a prime no.?

anonymous · Answer

yes I do.

anonymous · Answer

Like, a simplified fraction?

anonymous · Answer

Because that cannot be simplified any more.

anonymous · Answer

ok so for the first question, you have all you need there. 13 flaws our of 150 sweaters means 13/150 = probabilty of being flawed

anonymous · Answer

for the next two questions, you take the same probability (13/150 = X?) and multiply that probability by 600 and then 700 for each of those answers. does that make  sense?
