A coin is tossed twice. Ali claims that the event of two heads is at least as likely if we know that the first toss is a head than if we know that at least one of the tosses is a head. Is he right? Does it
make a difference if the coin is fair or unfair? How can we generalize Ali's reasoning?

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
