What is the experimental probability that a 10th grade student gets choosen

Hello there! 70% is your answer.

Since the question wants the the probabilities that the student has at least one, but not greater than 2 siblings, add the students that have 1 sibling and have two siblings, 10 + 18 =  28.

Since it can only be 28 students out of the total, put 28 over the total. 28/40, to convert into a percent, divide 28 by 40 and multiply by 100.

28 divided by 40 = 0.7

0.7 multiplied by 100 = 70%

So, the experimental probability that a student has at least one, but not greater than 2 siblings is 28/40 or 70%. I hope this was helpful and have a great rest of your day! :)

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
