Step-by-step explanation:
Answer:
<u>The correct answer is B. 2/5</u>
Step-by-step explanation:
This is the information given to us:
A. Shopping preferences for the survey:
1. Mall
2. Stand-alone store
3. Online
B. Paying preferences:
1. Store card
2. Credit card
3. Cash
4. Gift card
5. Check
Assume equal probabilities within categories.
It means that each of the paying preferences has the same probability of being selected, if there are five, it means each paying preference has 1/5 of probability and if we're choosing two of them: gift card or check, we have
<u>1/5 + 1/5 of probability = 2/5</u>
<u>The probability of paying by gift card or check is 2/5</u>
It's quite difficult, almost impossible to write all steps to solve a 3x3 matrix.
However, I will give you te answer that is determinant (Matrix)=54
This is an independent event because picking on book at random has nothing to do with picking the next book at random. The probability is 1/7
A= 67y+93/q-y; q=/0
