Answer:
15
Step-by-step explanation:
.5 * 30 = 15
270 divided by 3 = 90.
90 is the cost per person.
Now you do 90 times 10 to get the total for all 10 people.
90 times 10= 900.
Its 11/12 , you need to divide the "wanted results" (every dog which is either black, with spots or both ) by every every possible result ( all dogs ). so 11/12=0.92
