A diner asks patrons for their preference for waffles or pancakes and syrup or fruit topping.
prohojiy [21]

Answer:

P (Waffles | Syrup)\neq P(Waffles)

Step-by-step explanation:

From the table we have to:

Probability of syrup is 0.96

Probability of waffles and syrup is 0.32

P (Waffles | Syrup) = P (Waffles and syrup) / P (syrup)

So:

If this equality is met, the probabilities are dependent, if on the contrary

P (Wafles | Syrup) = P (Wafles) then are independent probabilities.

P (Wafles | Syrup) = 0.32 / 0.96 = 0.333 \neq 0.32

So we have to:

P (Waffles | Syrup)\neq P(Waffles)

The probabilities are dependent.

98 >= 35 + .21x
63 >= .21x
300 >= x
.
This says that if the total mileage is 300 miles or less he will be within his budget.
