A candy dish contains seven peppermints and four chocolates. Fred picks one candy randomly. What is the probability that it will not be a peppermint?
4 not peppermints, so
4/(7+4) = ___
4/11
To find the probability that Fred picks a candy that is not a peppermint, we need to determine the total number of candies in the dish and the number of candies that are not peppermints.
Total number of candies in the dish = 7 + 4 = 11 (7 peppermints + 4 chocolates)
Number of candies that are not peppermints = 4 (chocolates)
The probability of not picking a peppermint candy can be calculated as:
P(not peppermint) = Number of candies that are not peppermints / Total number of candies
P(not peppermint) = 4 / 11
So, the probability that Fred picks a candy that is not a peppermint is 4/11 or approximately 0.364 (rounded to three decimal places).
To find the probability that Fred picks a candy that is not a peppermint, we need to determine the total number of candies in the dish and the number of candies that are not peppermints.
First, we add the number of peppermints and chocolates: 7 + 4 = 11
So, there are 11 candies in total.
Next, we determine the number of candies that are not peppermints. Since there are 4 chocolates, there are 4 candies that are not peppermints.
Therefore, the probability of Fred picking a candy that is not a peppermint is given by:
Number of candies that are not peppermints / Total number of candies
So, the probability is: 4 / 11 ≈ 0.364
Therefore, the probability that Fred picks a candy that is not a peppermint is approximately 0.364 or 36.4%.
