M–[(m–n)÷(−2)](−5), if m=−4, n=−6
jeka94

Answer:

-9

Step-by-step explanation:

We are given the expression m–[(m–n)÷(−2)](−5).  Substituting -4 for m and -6 for n, we get:

-4–[(-4 + 6)÷(−2)](−5)

We must do the work that appears inside parentheses first:

-4–[(  2  )÷(−2)](−5)

Next we must do the work that appears inside square brackets:

-4–[     -1    ](−5)

                                             Multiplication comes next.  The above expression becomes:

-4 - [ 5  ]

which in turn comes out to -9

melamori03 [73]
To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10
