The bag contains 10+6+4=20 marbles, so the probability of selecting a red then a green in that order without replacement is:

(4/20)(6/19)=24/380

6/95  (≈6.32%)

Audrey and Sam divided money in the ratio of 3 to 5. Audrey obtained $36, how much money do they have altogether?
Ivenika [448]

8:20 is the same as 2:5.

<h3>What is unitary method?</h3>
  • The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units. What can be values and units.
  • Let's say you go to the store to buy six apples. You are informed by the shopkeeper that he is offering 10 apples for Rs 100. In this instance, the value and the units are the price of the apples.
  • Recognizing the units and values is crucial when using the unitary technique to a problem.
  • Always write the items that need to be computed on the right side and the things that are known on the left side to simplify things. We are aware of the quantity of apples and the amount of money in the aforesaid problem.

acc to our question-

  • = 12 + S
  • S= (2/5)A
  • S= (2/5)(12+S)
  • 5S = 24 + 2S
  • 3S = 24
  • S = 24/3 = 8 = what Sam received
  • A= 8+12 = 20 = what Audreyreceived
  • 8:20 is the same as 2:5
  • divide both 8 and 20 by 4 to get the 2 to 5 ratio.

hence,8:20 is the same as 2:5.
