Answer: Blood type will be A when event "A" happened and event "B" did not happen. Blood type will be B when event "A" did not happened and event "B" happened. Blood type will be AB when both events happened and blood type will be O when both events did not happen.

Step-by-step explanation:

S={AntiA reacts; AntiA does not react; AntiB reacts; AntiB does not react}

If AntiA reacts and AntiB reacts = AB (A∩B)

If AntiA does not react and AntiB does not react= O (A'∩B')

If AntiA reacts and AntiB does not react= A (A∩B')

If AntiA does not react and AntiB reacts= B (A'∩B)

You have $2 and earn $0.50 for each cup of lemonade you sell. Write an equation in two variables that represents the total amoun

Pani-rosa [81]

So because you will have $2 no matter how many cups you sell the equation starts off as AA = 2

Next, you add the dependent variable, because 1 cup of cc = $0.50 you add 0.5cc to the equation (it can also be written as 1/2cc), to complete the equation.
AA = 1/2cc +2
