You want to risk $100 on a bet that pays 2:3 (-150). How much will you win, risking $100?
Correct Answer: $150
Your Answer: $66.67

Explanation: 100 * odds (2/3) = 66.67. Another way to calculate this using moneylines: 100 * ( -100 / ml ) Or 100 * (- 100 / -150)

Correct Answer: $1000
Your Answer: $333.33

Explanation: The extra money is $1000 divided 3 ways. $1000 / 3 = 333.33.

I agree Tomato. There was another one that was wrong too.

The one about martingale betting system, it said if the guy could bet forever what would be his theoretical lose per bet.

My Answer was 0. It said Answer was Infinity.

If he can bet forever, he would never lose in a martingale system thus lose would be 0

If you bet on red on a roulette wheel 100 times, you could have 100 losses. If you bet on a roulette wheel ∞ times, you could have ∞ losses. The theoretical loss is the same whether you bet 1 or ∞ times.

If you think the theoretical loss is equal to zero in the question then you must also think that you can reduce the house edge the more you play. And you know that's not true.

It's a complex question... I wish you'd post the explanation (I don't remember what I wrote years ago), but when dealing with products in infinite series, you have to use "infinite cardinal arithmetic". Your theoretical loss keeps going up, even though you're sure you will eventually win.
