Ответ:
Expected amount is loss of 0.167 $.
Step-by-step explanation:
Probability is the ratio of number of favorable outcome to total number of outcomes.
Total number of outcomes = 6, since the die has 6 faces.
If the die comes up 1, the player wins $2. If the die comes up 2, the player wins $1. For all other outcomes, the player loses $1.
Now we need to find expected amount that the player wins or loses.
Expected amount = ∑Probability of event x Winning or losing on that event
Expected amount is loss of 0.167 $.
