In a group of 55 people, 33 are coffee drinkers and 12 are tea drinkers. Assuming that no one in this group drinks both tea and coffee, what is the probability that a person picked at random from the group does not drink tea or coffee?
Answers
Answer:
The probability that a person does not drink tea or coffee is 2/11.
Step-by-step explanation:
Always the probability will be less than one, as per the definition of probability.
Total number of people in a group = 55
Coffee drinkers = 33
Tea drinkers = 12
Total number of people drink coffee and tea = 33+12
=45
Probability of people randomly drink either coffee or tea = 45/55
Probability of people randomly drink neither coffee or tea = 10/55 = 2/11
Hence the probability in terms of decimal is 0.1818
Answer:
The probability that a person does not drink tea or coffee is 2/11.
Always the probability will be less than one,as per the definition of probability.
Total number of probability in a group = 55
Coffee drinkers = 33
Tea drinkers = 12
Total number of people who drink coffee and tea = 33+12
=45
Probability of people randomly drink neither coffee or tea = 10/55=2/11
Hence the probability in terms of decimal is 0.1818.
