In a survey, 169 respondents say that they never use a credit card, 12527 say that they use it sometimes, and 2834 say that they use it frequently. find the probability that a randomly selected person uses a credit card frequently (round to 4 decimals) then take that result and decide whether it is likely or unlikely (only type in the word! ) for someone to use a credit card frequently.

Probability: 0.1825 or 18.25%  .......  Unlikely

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Probability problems.

To start of we need to calculate the total amount of respondents that took the survey. We do this by adding all the answers together.

169 + 12,527 + 2,834 = 15,530 total people

Now that we know the total amount of people we can calculate the probability of each response by dividing the amount of people that had that response by the total amount of people that took the survey.

Never Used:

Sometimes Used:

Frequently used:

So we can see that the probability of a randomly selected person using a credit card frequently is 0.1825 or 18.25%

Unlikely

I hope this answered your question. If you have any more questions feel free to ask away at .

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

i think it is c hope that
