Mario likes to eat at a local restaurant but he has difficulty choosing his meal as he likes 6 main courses equally and there are two desserts he loves. He decides to roll a die to choose his main course and flip a coin to decide his dessert. He assigns the meal this way; chicken parmigiana as 1, chilli prawns as 2, spaghetti Bolognese as 3, grilled barramundi as 4, pepper steak as 5 and spicy calamari as 6. He assigns his desserts this way: sticky date pudding as H and tiramisu as T. Find the probability that he chooses:
a) Chicken parmigiana and tiramisu

What is the probability for each individually?
OpenStudy (anonymous):
1/12? I am not sure
OpenStudy (fibonaccichick666):
For the final answer of the question I asked?
OpenStudy (anonymous):
for the chicken parmigiana is it 2/12 and the tiramisu 6/12?
OpenStudy (fibonaccichick666):
not quite, Simplify those. Where did you get 12 from?

I thought that 12 comes from the number of possibilities
OpenStudy (fibonaccichick666):
How many options do you have for food?
OpenStudy (anonymous):
6 and 2 for desserts
OpenStudy (fibonaccichick666):
So what chance do you have of getting chicken parm alone?
OpenStudy (anonymous):
1/12

1/2
OpenStudy (fibonaccichick666):
Correct, now are these events separate?
OpenStudy (anonymous):
yes
OpenStudy (fibonaccichick666):
So when we have separate events, what do we do to their probabilities?
OpenStudy (anonymous):
add then together?

them*
OpenStudy (fibonaccichick666):
No, not quite.
OpenStudy (fibonaccichick666):
I can't think of a good example where you use addition, but no it's not addition.
OpenStudy (anonymous):
I'm not sure what you would use
OpenStudy (fibonaccichick666):
Well, what is the other thing that we use?

multiplication?
OpenStudy (fibonaccichick666):
Yeppers
OpenStudy (anonymous):
so do I multiply 1/2 and 1/6 together
OpenStudy (anonymous):
yes
OpenStudy (fibonaccichick666):
That would be correct

so is the answer 1/6?
OpenStudy (fibonaccichick666):
What is the product of \(\frac{1}{2} ~and~\frac{1}{6}\)
OpenStudy (anonymous):
2/12
OpenStudy (fibonaccichick666):
Where did you get the 2 from?
OpenStudy (anonymous):
1/12

First show me your work before I tell you if it's right. (Explain the multiplication)
