Answer:
b
Step-by-step explanation:
The sum of 2 and y is 2 + y, then 4 times this sum is
4(2 + y) → b
Answer:
4/x-1 is the correct answer
Step-by-step explanation:
Answer:




And then replacing we have this for the expected value:

And after do the math we got:

And then the expected value for this game is -0.79998 a negative result means NOT a win.
Step-by-step explanation:
For this case we can define the random variable X as the amount that we can win. We can find the expected value with the following formula:

And we have the following probabilities and possible values given:




And then replacing we have this for the expected value:

And after do the math we got:

And then the expected value for this game is -0.79998 a negative result means NOT a win.
