There is a committee to be selected comprising of 5 people from a group of 5 men and 6 women. Whether the selection is randomly done then determines the possibility of having the given possibilities combinations
i. One particular man and one particular woman should not be in the committee (one man four women)
Solution
i. P(one particular man and one particular woman should not be in the committee would be determined as given below:
The group size = 5m + 6w
Committee size = 5 people
Actual groups size from which to
Select the committee = 4m + 5w
Committee = 1m + 4w
The committee may be selected in 9C5
The one man may be selected in 4C1 ways
The four women may be selected in 5C4 ways
∴ P(committee of 4w1man).
(5C4 * 4C1) = 9C5
= 10/63
x 4 - 25 There is no greatest common factor here. Though, notice that it is the difference of two perfect squares. x 4 - 25 = ( x 2 ) 2 - (5) 2 Thus, we can employ
why zero factorial is equal to one
There are really three various methods for doing such integral. Method 1: This method uses a trig formula as, ∫sin(x) cos(x) dx = ½ ∫sin(2x) dx = -(1/4) cos(2x) + c
Linear Approximation Method This is a rough and ready method of interpolation and is best used when the series moves in predicted interval
∫1/sin2x dx = ∫cosec2x dx = 1/2 log[cosec2x - cot2x] + c = 1/2 log[tan x] + c Detailed derivation of ∫cosec x dx = ∫cosec x(cosec x - cot x)/(cosec x - cot x) dx = ∫(cosec 2 x
Correlation coefficient - These are numerical measures of the correlations existing between the independent and the dependent variables - These are better measures of corre
