Question

Twenty students choose a piece of fruit from a list of 4 fruits: apple banana grape and pear. The theoretical probability that a student will choose a banana is. .25. Only 1 student chooses a banana how many can the exerpimental probability get closer to the theoretical probability

Answer 1

Answer:

Significant difference of 0.20

Step-by-step explanation:

No of student = 20

No of fruits available =4

EAch student is independent of the other.

Hence theoretical probability that a student will choose a banana is=1/4=0.25.

But actual experiments showed that only 1 student selected banana out of 20

Experimental probability that a student will choose a banana is.=1/20 =0.05

The difference between the two = 0.25-0.05 = 0.20

Thus there is a significant difference between Experimental probability that a student will choose a banana and theorical probability that a student will choose a banana

Answer 2

Answer:

Only give two choices of fruit.
