The probability that a student prefers hamsters is approximately 0.21 or 21%. Therefore, the answer is C.
explain
To find the probability that a student prefers hamsters, we can look at the frequency of students who chose hamsters as their favorite pet and divide that number by the total number of students surveyed. According to the table, 42 students chose hamsters out of a total of 200 students surveyed.
So, the probability of a student choosing hamsters is:
probability = number of students choosing hamsters / total number of students surveyed
probability = 42/200
probability ≈ 0.21
Therefore, the probability that a student prefers hamsters is approximately 0.21 or 21%. Hence, the answer is C.
So, the probability of a student choosing hamsters is:
probability = number of students choosing hamsters / total number of students surveyed
probability = 42/200
probability ≈ 0.21
Therefore, the probability that a student prefers hamsters is approximately 0.21 or 21%. Hence, the answer is C.
your wrong its 8 student chose hamster out of 49
I apologize for my previous response, I must have misunderstood the data provided.
If the number of students who chose hamsters is 8 out of a total of 49 students surveyed, then the probability of a student choosing hamsters is:
probability = number of students choosing hamsters / total number of students surveyed
probability = 8/49
probability ≈ 0.16
Therefore, the approximate probability that a student prefers hamsters is 0.16 or 16%. The answer is A.
If the number of students who chose hamsters is 8 out of a total of 49 students surveyed, then the probability of a student choosing hamsters is:
probability = number of students choosing hamsters / total number of students surveyed
probability = 8/49
probability ≈ 0.16
Therefore, the approximate probability that a student prefers hamsters is 0.16 or 16%. The answer is A.
you better be right
I can assure you that the new answer of 0.16 (16%) is correct based on the given data that you provided. I apologize for any confusion caused by my earlier response.

The experimental probability of the coin landing on heads can be calculated by dividing the number of times the coin landed on heads by the total number of tosses.
In this case, the number of times the coin landed on heads is 27, and the total number of tosses is 50.
So, the experimental probability of the coin landing on heads is:
27/50
which simplifies to 0.54 or approximately 54%.
Therefore, the answer is C, 27/50.

Therefore, the answer is C, 27/50.
