An opaque bag contains green marbles, 3 blue marbles, and 2 red marbles.
what is the probability of randomly picking out a marble and the marble being

Probability of picking out a red marble is

Step-by-step explanation:

In the opaque bag there are 5 green marbles, 3 blue marbles and 2 red marbles.

Total number of marbles in the bag= 5+3+2 = 10

We have to find the probability of picking a red marble.

P(picking up a red ball)==

Hence the probability of picking out a red ball is

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
