The probability of drawing two blue marbles if the first marble is not replaced is 1/5
<h3>How to determine the probabilities?</h3>
<u>The probability of tossing a head and drawing a red marble</u>
The given parameters are:
White = 1
Blue =3
Red = 2
Total = 6
The probability of a head is
P(Head)= 1/2
The probability of drawing a red marble is
P(Red)= 2/6 = 1/3
The required probability is
P = P(Head) * P(Red)
This gives
P = 1/2 * 1/3
P =1/6
<u>The probability of drawing two blue marbles if the first marble is not replaced.</u>
Here, we have:
P(B1) = 3/6 = 1/2
P(B2) = 2/5
The required probability is
P = P(B1) * P(B2)
This gives
P = 1/2 * 2/5
P =1/5
Hence, the probability of drawing two blue marbles if the first marble is not replaced is 1/5

Answer:
-4 mph/sec
Step-by-step explanation:
In the problem it is already given that the average rate of inflation per year between 2005 and 2009 is 2.2%. the price of the product in 2005 is $120. It is required to find the rate of the product in the year 2009.
In the year 2006 rate of increase of the product price = 120 * (2.2/100) dollars
= 2.64
Then price in 2006 = (120 +2.64) dollars
= 122.64 dollars
In the year 2007 rate of increase of the product price = 122.64 * (2.2/100) dollars
= 2.69 dollars
Then price in 2007 = 125.34 dollars
In the year 2008 rate of increase of the product price = 125.34 * (2.2/100)
= 2.75 dollars
Then price in 2008 = 128.09
In the year 2009 rate of increase of the product price = 128.09 * (2.2/100) dollars
= 2.82 dollars
Then the price in 2009 = 130.91
In the year 2009 the product cost $130.91
