Answer:
495 combinations of 4 students can be selected.
Step-by-step explanation:
The order of the students in the sample is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
How many combination of random samples of 4 students can be selected?
4 from a set of 12. So
495 combinations of 4 students can be selected.
13^6 you whould have to move the decimal over 6 times :)
5: six twelfths is one half
6: eight tenths is four fifths
7: four eighths is one half
8: ten tenths is two halves
9: two sixths is one third
10: one quarter, because you divide the top and bottom number by 3
method:
take the first one - four eighths, which is 4/8
the question gives you what to divide them by, 4, so u divide both the top number and bottom number to get 1/2, which is one half :)
