These marbles are placed in a bag and two of them are randomly drawn what is the probability of drawing two yellow marbles if the first one is placed back before the second draw. write your answer as a ratio. reduce to simplest terms

Probability of drawing two yellow marbles if the first one is placed back before the second draw is 1 : 5.

Step-by-step explanation:

Given:

Number of yellow marbles  = 2

Number of pink marbles  = 3

Number of blue marbles  = 5

Total number of marbles = 10

To Find:

Probability of drawing two yellow marbles if the first one is placed back before the second draw = ?

Solution:

Let

P(A)  be the probability of drawing the first marble

P(B) be the probability of drawing the second marble.

Similarly

Since the first one is placed back before the second draw.

Now  P(A) and  P(B) are independent event

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
