The oods in favor of jim beating a friend golf are 1: 8, find the probability that jim wins

Probability that Jim wins is given by

Step-by-step explanation:

Since we have given that

The odds in favor of Jim beating a friend golf are 1:8.

Let A be the event that Jim beating a friend golf.

So, according to ratio, it becomes,

P(A) = 1x

P(A') = 8x

And we know that

P(A)+P(A')=1

That implies

Hence, Probability that Jim wins is given by

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
