Answer:
a) N = 240 ways
b) N = 303,600 ways
c) N = 10 ways
Step-by-step explanation:
a) Given
General course consist of one course from each of 4 groups.
Social Science = 5 options
Humanities = 4 options
Natural sciences = 4 options
Foreign language = 3 options.
Therefore the total number of possible ways of selecting one each from each of the 4 groups is:
N = 5×4×4×3 = 240 ways
b) if four people are chosen from 25 member for four different positions, that makes it a permutation problem because order of selection is important.
N = nPr = n!/(n-r)!
n = 25 and r = 4
N = 25P4 = 25!/(25-4)! = 25!/21!
N = 303,600 ways
c) The number of ways by which 5 tosses of coin can yield 2 heads and 3 tails.
N = 5!/(5-5)!(2!)(3!)
N = 5×4/2
N = 10 ways
How many employees are there in total?
Answer:
50 in, 48 in, 14 in.
Step-by-step explanation:
If it's a right triangle then it will fit the Pythagoras theorem
c^2 = a^2 + b^2 where c is the hypotenuse.
50^2 = 2500
48^2 = 2304
14^2 = 196
2304 + 196 = 2500.
So its the second choice.
Hope this helps.
