Answer: If I were you, I would guess 320 students.

Step-by-step explanation:

1.) Think about it, 400 students were asked the same question and 80 chose to fight for lemonade on the school menu. 4/5 or 320 students put Guess.

2.) It's true that 400 students voted, but 80 voted yes, and 320 voted guess.

3.) Further Explanation:

1/5 times 400 equals 80. It's true only 80 students voted yes. 4/5 times 400 equals 320 students voted guess.

The world famous gambler from Philadelphia, Senor Rick, proposes the following game of chance. You roll a fair die. If you roll
Orlov [11]

Answer:

You lose $0.833 while Rick gains $0.833, and so Rick is not Loco

Step-by-step explanation:

There are six numbers on a dice. Thus, probability of rolling exactly one number = 1/6

Probability of rolling two is 2/6.

Rolling a 1 pays $25, and probability = 1/6

Rolling a 2 pays $5,and probability = 1/6

Rolling a 3 pays $0, and probability = 1/6

Rolling a 4 or 5 pays -$10, and probability = 2/6

Rolling a 6 pays -$15, and probability = 1/6

Thus,lets calculate the expected value;

EV = (25 × 1/6) + (5 × 1/6) + (0 × 1/6) + (-10 × 2/6) + (-15 × 1/6)

EV = - $0.833

This means you lose $0.833 while Rick gains $0.833, and so Rick is not Loco.
