probability of getting heads is = 1/2 there for 10 tosses its (1/20)^10
Ответ:
The answer is A.
Step-by-step explanation:
If Mark earns 1250 for selling a 25000 car, that means he earns 5% commision because 1250 divided by 25000 is 0.05. And 0.05 equals 5%. Then you just try each of the answers. Since 15000 times 0.05 does equal 750, that means answer A has the same proportion as the example in the question.
