In a consumer survey, 10 people were asked to choose a cola among Coke, Pepsi, and RC. If each person chose a cola randomly, what is the probability that at least one person did not choose Coke

Answers

The Probability that at least one person did not choose Coke is 7/10.

According to the statement

we have given that the in a consumer survey, 10 people were asked to choose a cola among Coke, Pepsi, and RC.

And we have to find the probability that at least one person did not choose Coke.

So, for this purpose, we have know that the

Probability is the chance that a given event will occur.

In probability, at least mean the minimum value that should occur once a random event happens.

And

the number of person which take part in a survey = 10

Number of items to choose = 3

The probability that the all person choose cola = 3/10

And

we know that the at least probability is:

at least probability = 1 – simple probability

So,

Probability that at least one person did not choose Coke = 1 – Probability that all person did choose Coke

Substitute the values in it then

Probability that at least one person did not choose Coke = 1 – 3/10

Probability that at least one person did not choose Coke = 7/10.

So, The Probability that at least one person did not choose Coke is 7/10.
