Out of 10students the favourites drinks of seven is coke and a favourite drinkof kthe rest is Fanta a teacher picks a student at random what is the probability that the favourite drink of the is
I'd guess either 7/10 or 3/10, depending on how you finish the question.
Well, if the favorite drink of seven out of ten students is Coke, and the favorite drink of the rest is Fanta, then the probability that the favorite drink of the randomly picked student is Coke would be 7 out of 10. So, the probability would be 7/10, or you can say it's about 70%. Although, keep in mind that there might be some students who just enjoy clown tears instead! Who knows?
To find the probability, we need to determine the number of favorable outcomes (picking a student whose favorite drink is Fanta) and the total number of possible outcomes (picking any student).
Given that out of 10 students, the favorite drink of 7 is Coke and the favorite drink of the remaining students (3) is Fanta, we know that the number of favorable outcomes is 3.
The total number of possible outcomes is the total number of students, which is 10.
Therefore, the probability of picking a student whose favorite drink is Fanta is:
Probability = Favorable outcomes / Total outcomes
Probability = 3 / 10
Probability = 0.3 or 30%
To find the probability that the favorite drink of the chosen student is Coke, we need to determine the total number of students and the number of students who prefer Coke.
Given that there are 10 students in total, and 7 of them prefer Coke, we can calculate the probability.
Probability = Number of favorable outcomes / Total number of outcomes
Favorable outcomes: Number of students who prefer Coke = 7
Total outcomes: Total number of students = 10
Therefore, the probability that the favorite drink of the chosen student is Coke is:
Probability = 7/10
Simplifying the fraction, the probability is:
Probability = 0.7
So, there is a 0.7 (or 70%) chance that the chosen student's favorite drink is Coke.
