in an experiment, it was found that 70 out of 800 animals were happy in their surroundings.
a find probability that an individual animal is happy in their surroundings.
b. represent as a percent
Now Thomas!
What do you think?
This one is even easier than the other ones you posted.
How about showing us your work?
70/800
70/800 8.75%
correct
In order to find the probability that an individual animal is happy in their surroundings, we can use the ratio of the number of happy animals to the total number of animals in the experiment.
a. The probability is calculated as the number of happy animals divided by the total number of animals:
Probability = Number of happy animals / Total number of animals
In this case, we are given that 70 out of 800 animals were happy. Therefore, the probability can be calculated as follows:
Probability = 70 / 800
b. To represent the probability as a percent, we can multiply the probability by 100:
Percentage = Probability × 100
Using the calculated probability, we get:
Percentage = (70 / 800) × 100
Simplifying this calculation, we find the percentage of animals that were happy in their surroundings.
