Answer:

(b) 5.

Step-by-step explanation:

The bottom numbers are calculated from the 2 above them according to the formula:

c =  15(a + b)

- because:  75 = 15(2 + 3) and  

165 = 15(7 + 4)    

Therefore if the unknown number is x :

285 = 15(14 + x)

285 = 210 + 15x

15x = 285 - 210

15x = 75

x = 5.

Merrill is playing a simple game of dice. For every 6 rolled, Merrill will win $5. For any other number, he must pay $2. How muc
Schach [20]

Solution -

The probability of getting 6 from a single roll of a fair dice = \frac{1}{6}

The probability of getting any other number rather than 6 would be 1-\frac{1}{6} = \frac{5}{6}

So when the outcome is 6, then he wins $5 ,otherwise he has to pay $2

So

E(X) = Expectation value = (\frac{1}{6} )(5) - (\frac{5}{6} )(2)                                    ( ∵ $5 gain so +ve and $2 loss so -ve)

=\frac{-5}{6}

∴ So Merrill will lose \frac{5}{6} dollar
