A bag contains only red , yellow brown and green marbles the probabilities of selecting each colour are below
red - 5x
green - 2x
brown - 3x
yellow - 4x
find the probability of selecting a green marble

1/7

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur. this is expressed as;

Probability = Expected outcome/Total outcome

From the question, the total number of marbles is the total outcome

Total outcome = 5x + 2x + 3x + 4x

Total outcome = 14x

Since we are to find the probability of selecting a green marble, the expected outcome will be total number of green marbles which is 2x

Pr(selecting green marbles) = 2x/14x

Pr(selecting green marbles) = 1/7

Hence the probability of selecting a green marble is 1/7

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
