You are challenged to a lucky draw game. If you draw a face card (K, Q, J) from a standard deck of cards, you earn 10 points. If
Aleksandr [31]

The Expected value of a draw from the given question is; A; 0.77

We are told the face cards are K, Q, J. This means that there are 3 face cards for each of the 4 suits.

Since you earn 10 points for each face card, it means that;

total possible gain = 10 × 3 × 4 = 120

In a deck of cards, there are a total of 52 cards.

This means that;

Number of cards that are not K, Q or J = 52 - (4 × 3) = 40

Since 2 points are lost for drawing any of this 40 cards, then;

Total possible loss = 40 × 2 = 80

Expected gain = 120 - 80

Expected gain = 40

Expected value of a draw = 40/52

Expected value of a draw = 0.77

What is the difference in volume between a sphere with radius r and a sphere with radius 0.3r?
REY [17]
The volume of the sphere of radius r is:
 V1 = (4/3) * (pi) * (r ^ 3)
 Where,
 r: sphere radius:
 The volume of the sphere of radius 0.3r is:
 V2 = (4/3) * (pi) * ((0.3r) ^ 3)
 Rewriting:
 V2 = (4/3) * (pi) * (0.027 (r) ^ 3)
 V2 = 0.027 (4/3) * (pi) * (r ^ 3)
 V2 = 0.027V1
 The difference is:
 V1-V2 = V1-0.027V1 = V1 (1-0.027)
 V1-V2 = 0.973 * (4/3) * (pi) * (r ^ 3)
 Answer:
 
the difference in volume between a sphere with radius and a sphere with radius 0.3r is:
 
V1-V2 = 0.973 * (4/3) * (pi) * (r ^ 3)
