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:
x=-7
Step-by-step explanation:
x+8=1
- Subtract 8 from both sides.
Answer:
The length of the winhspan of aeroplane is 45 m
Using the combination formula, it is found that there are 220 ways to decide which countries to skip.
The order in which the countries are skipped is not important, hence the <em>combination formula </em>is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:
In this problem, 3 countries are skipped from a set of 12, hence the number of ways is given by:
