Answer:
$0.0646 is the expected value of the draw.
Step-by-step explanation:
1 nickel = 5 cents
1 dime = 10 cents
1 penny = 1 cent
Total number of coins = 
Probability that a nickel is selected is = 14/35
Probability that a dime is selected is = 15/35
Probability that a penny is selected is = 6/35
So, the expected value of the draw will be =

= 6.457 cents ≈6.46 cents
So, in dollars it is =
= $0.0646
So, $0.0646 is the expected value of the draw.
17 -12x - 18 - 5x=
-1 - 17x =
-1 = 17x
What do you mean "how many"? Like how many different rotations can you do and it'll be the same or just symmetries in general?
