So the sale price was $160 and the shipping fee was $8.
They are asking what percent of the sales price was the shipping fee...
or in other words, what percent of 160 is 8?
Divide 8/160
You should get 0.05, or 5% :)
2.34 because 23.47 times .10 which is 10% of the tip would be 2.34
So okay, in stats when there is probability that looks like p(fem/type b) it means what is the probability that they are female given they are type b, so it would be where they intersect. Therefore where they intersect on the table is 22 out of the total of 200 people so 1/10. Now that we know that probability let's look at the "or" one, when it says or it means it could be a female or a type b so we would include both totals of each:
97 females+70 type b= 167
now we divide that by the total amount of people so it simplifies down to a probability of 0.835.
Finally, looking at these 2 probability we can see that the "or" probability is far greater than the one previous discussed so it would be the last option if I remeber correctly!!
