a storeowner made a list of the number of greeting cards sold last month. The store sold 167 thank you cards, 285 birthday cards, and 56 blank cards. Based on this data, which number is closest to the probability that the next costumer will buy a blank card?

Well to solve this we can take 167+285+56=508 then we can take 56/508=.11 to find the probability that the next user will buy a blank card, meaning that there is a 11% probability that the next customer will buy a blank card.

Answer: There is 11% chance that the next costumer will buy a blank card.

Explanation:

Since we have given that

Number of thank you cards = 167

Number of birthday cards = 285

Number of blank cards = 56

So, Total number of cards is given by

167+285+56=508

So, Probability that the next costumer will buy a blank card is given by


(56)/(508)\\\\=0.110* 100\\\\=11\%

Hence, there is 11% chance that the next costumer will buy a blank card.
