Its a simple unitary method problem…
6 men will do the work in 12 days
1 man will do in 6*12 = 72 days
So, 5 men will do it in 72/5 = 14.4 days
There are two types of relation
<span>Direct relation - If one quantity increases then the other also increases and if one quantity decreases then the other also decreases.</span>
Example- If 3 pencils cost Rs 7, then what will be the cost of 5 pencils ?
3 pencils cost Rs 7
1 pencil will cost Rs 7/3 (First divide)
5 pencils will cost Rs (7/3)*5 = Rs 11.66 (Then Multiply)
<span><span>Inverse relation : </span>If one quantity increases then the other decreases and if one quantity decreases then the other increases.</span>
Example - This question itself is the example of inverse relation. Here first we did multiplication and then division.
I hope it clears the image….
9 + 6 = 15 so its 15 i think
The volume alone is not sufficient to specify the dimensions.
It might be 18 in square and 9 in high.
A) The possible three-course selections are as shown below.
B) The likelihood of selecting the combinations is 0.1 since there are 10 combinations in total.
<h3>How to solve probability combinations?</h3>
A combination operator can be used when we need to find the number of ways to select "k" items from a set of "n" items. It is also called a 'choose' operator where it is read as 'n choose k' and is represented and calculated as given below
From the choices given, there are 5 courses which are given below:
EPR 605
EPR 643
EPR 648
EPR 674
EPR 681
We need to find the combinations of 3 of these given 5 courses, which are given below (omitting the course code, EPR):
605-643-648
605-643-674
605-643-681
605-648-674
605-648-681
605-674-681
643-648-674
643-648-681
643-674-681
648-674-681
10 of the given choices of combinations are possible since they do not include a repeated course number.
The likelihood of selecting the combination of EPR 681, EPR 648, and EPR 605 is 0.1 since there are 10 combinations in total.
Complete question is;
A student entering a doctoral program in educational psychology is required to select three courses from the list of courses provided as part of his or her program.
