Hello please help with my probability homework. 1.a)Kali orders the sirloin tips at Hoss'. She can pick between the 10 oz, 8 oz or the 6 oz portion. She can choose to have her steak prepared rare, medium rare, medium, medium well, or well done. She can also have her sirloin tips served with or without each of three toppings: sautéed onions, peppers or mushrooms. Kali may also choose from one of 7 side dishes. How many possible dinners are there when ordering the sirloin tips?

b)If you drew the factor tree of problem #a, how many end branch tips would there be ?

c)Given that she orders an 8 oz steak with mashed potatoes with gravy as her side dish, what is the probability that Kali orders a steak dinner which is rare but does not have sautéed onions ?​
