Out of 10 students, the favorite drink of seven students is Coke and the favorite drink of the rest is Fanta. A teacher picks a student at random. What is the probability that the favorite drink of the student is: Coke?
To find the probability, we need to divide the number of outcomes in which the student has Coke as their favorite drink by the total number of possible outcomes.
Given that there are 10 students in total, and out of these 10, 7 have Coke as their favorite drink, the number of outcomes in which the student has Coke as their favorite drink is 7.
Therefore, the probability of a student having Coke as their favorite drink can be calculated as:
Probability = Number of outcomes with Coke as favorite drink / Total number of possible outcomes
Probability = 7/10
Hence, the probability that the favorite drink of the student is Coke is 7/10, or 0.7, which is equivalent to 70%.
Since 7 of the 10 students like Coke,
the prob(a student likes Coke) = ....
