17. suppose a lottery ticket costs $1 and the probability that a holder will win nothing is 90%. what must the jackpot be for this to be a fair bet?

10 dollars

Step-by-step explanation:

That would make sense if $1 is 10 percent meaning 1/10 people have a chance of winning

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
