Answer:
Check the explanation
Step-by-step explanation:
The odds are 4 to 1 against, so we can estimate the probability of success (p) as
The expected pay for every success is 3 to 1, so we lose $1 for every lose and we gain $3 for every win.
The number of winnings in the 100 rounds to be even can be calculated as:
We have to win at least 25 rounds to have a positive payoff.
As the number of rounds is big, we will approximate the binomial distribution to a normal distribution with parameters:
The z-value for x=25 is
The probability of z>1.25 is
P(X>25)=P(z>1.25)=0.10565
There is a 10.5% chance of having a positive payoff.
NOTE: if we do all the calculations for the binomial distribution, the chances of having a net payoff are 13.1%.

Answer:
$850
Step-by-step explanation:
Let 'P' be the purchase of the computer.
Jasmine paid 7.5% sales tax on the purchase price (P) of the computer, and she paid $63.75 in sales tax, your equation will be:
7.5%P=$63.75 which is also .075P=$63.75
1000(.075P)=1000($63.75)
75P=$63,750
75P/75=($63,750)/75
(75/75)P=($63,750)/75
(1)P=($850.00)
P=$850.00
