Area of trapezium=(1/2)×(a+b)h

A=33

a=2

b=?

h=6

(1/2)(2+b)(6)=33

(1/2)(12+6b)=33

6+3b=33

3b=33-6

3b=27

b=27÷3

Answer:

5 cents

Step-by-step explanation:

So the roulette wheel would have a total of 38 numbers, which means 38 different possible cases. Since you are allowed to bet on 5 numbers, the chance to win this is 5 out of 38 and to lose this is 33 out of 38.

If you win, you get 1 + 6 = 7 dollar, and if you lose, you lose 1 dollar.

Therefore the expected amount out of this game is:

$E = 7\frac{5}{38} - 1\frac{33}{38} = \frac{35}{38} - \frac{33}{38} = \frac{2}{38} = \frac{1}{19} = \$0.0526$

or 5 cents
