A bag contains 3 red, 6 blue, 5 purple, and 2 orange marbles. One marble is selected at random. What is the probability that the

Answer:

$P(blue)=37.5\%$

Step-by-step explanation:

-Probability is the likelihood of an event occurring.

-The total number of events is:

$Total=3+6+5+2\\\\=16$

-The total number of blue events is:

$Blue=6$

#Probability of a blue is thus calculated as:

$P(Blue)=\frac{Blue}{Total}\\\\=\frac{6}{16}\\\\=0.375\\\\=37.5\%$

Hence, the probability of choosing a blue marble at random is 37.5%

The answer is 12.8 cm³

<span>The volume ( v) of a gas in a container at a constant temperature varies inversely as the pressure (p):
v = k/p
p * v = k (k - constant)

p1v1 = k
p2v2 = k
So, p1v1 = p2v2

v1 = 24 cm</span>³
p1 = 16 lb
v2 = ?
p2 = 30 lb

24 * 16 = x * 30
384 = x * 30
x = 384 / 30
x = 12.8 cm³
