When playing roulette at a​ casino, a gambler is trying to decide whether to bet $5 on the number 25 or to bet $5 that the outco
USPshnik [31]

Answer:

a) -$3.03; b) The $5 on the number 25

Step-by-step explanation:

To find the expected value, multiply each probability by its value and then add them together.

The probability of making a profit of $20 is 3/38; this gives us

3/38(20) = 60/38

The probability of losing $5 is 35/38; this gives us

35/38(-5) = -175/38

Together, this gives us

60/38-175/38 = -115/38 ≈ $-3.03

b) Since the expected value for the $5 bet on a single number is $-0.53, and the expected value for the $5 on either 00, 0 or 1 is $-3.03, the better bet is on the number 25.  The expected value loses less money with this option.

It's easy it's called Two-way tables please help
Vesnalui [34]

Answer: The filled out table is shown below in the attached image

===========================================================

Explanation:

The letters A through J are one way to fill out the table. Though there are other possible orders.

Start at letter A, which is from the fact we have 40 people total

Then move to letter B. This is the total number who like pasta (26)

We have C = A-B = 40-26 = 14 people who don't like pasta

--------------

Now move to cell D. This is the total who don't like netball, which is 21 people. There are E = A-D = 40-21 = 19 people who do like netball.

F = 4 is the number of people who don't like either thing (netball or pasta). So G = D-F = 21-4 = 17 people like pasta but don't like netball.

Of those people who like netball (E = 19), we have 9 who also like pasta. This is in cell H in the upper left corner. This means J = E-H = 19-9 = 10 people like netball but don't like pasta.

----------------

So we have these values

  • A = 40
  • B = 26
  • C = 14
  • D = 21
  • E = 19
  • F = 4
  • G = 17
  • H = 9
  • J = 10
