The probability of selecting a blue marble is <u>3/14</u>. Hence, <u>option D</u> is the right choice.
The probability of any event is the chance of the occurrence of that event. It is given as the ratio of the number of favorable outcomes to the event to the total number of outcomes possible in the experiment.
If we consider an event A, the number of favorable outcomes to event A be n, and the total number of outcomes be S, then the probability of event A is given as:
P(A) = n/S.
Let us take the event of selecting a blue marble from the experiment of selecting a marble randomly from the bag be A.
The number of outcomes favorable to event A (n) = 3 {3 blue marbles}.
The total number of outcomes (S) = 14 {Total number of marbles in the bag = 4 red + 3 blue + 7 green = 14 marbles}.
Therefore, the probability of selecting a blue marble is,
P(A) = n/S = 3/14.
Hence, <u>option D</u> is the right choice.

Answer:
The pitcher plant's approximate volume is 24.492
.
Step-by-step explanation:
We are given that a pitcher is shaped like a cylinder with a radius of 1 centimeter and a height of 7.8 cm.
Let the radius of a cylinder = r = 1 cm
and the height of a cylinder = h = 7.8 cm
As we know that the volume of a cylinder is given by;
The volume of a cylinder = 
=
{taking approximate value of
to be 3.14}
= 
= 24.492 
Hence, this pitcher plant's approximate volume is 24.492
.
