A bag of mixed nuts contains 18 pecans, 18 walnuts, and 18 almonds. What is the probability of NOT randomly selecting a pecan from the bag?
To find the probability of NOT selecting a pecan, we need to find the total number of nuts in the bag and then subtract the number of pecans.
Total number of nuts = 18 pecans + 18 walnuts + 18 almonds = 54 nuts
Number of pecans = 18
Probability of NOT selecting a pecan = (Total number of nuts - Number of pecans) / Total number of nuts
= (54 - 18) / 54
= 36 / 54
= 2 / 3
Therefore, the probability of NOT randomly selecting a pecan from the bag is 2/3 or approximately 0.67 or 67%.
