Answer:

465 ways

Explanation:

Atleast 1 girl and 1 boy

Possible combinations :

1 girl ; 3 boys = 6C1 ; 6C3

2 girls ; 2 boys = 6C2 ; 6C2

3 girls ; 1 boy = 6C3 ; 6C1

(6C1 * 6C3) + (6C2 * 6C2) + (6C3 * 6C1)

Combination formula:

nCr = n! ÷ (n-r)!r!

We can also use a calculator :

6C1 = 6

6C3 = 20

6C2 = 15

Hence,

(6C1 * 6C3) + (6C2 * 6C2) + (6C3 * 6C1)

(6 * 20) + (15 * 15) + (20 * 6)

120 + 225 + 120

= 465 ways

Invalid length parameter passed to the LEFT or SUBSTRING function (below)".
Alla [95]

This error occurs when the number of arguments sent to the function are not equal ( greater or less ) to the parameters of the function.

For example:

// if the function is

void a_function(int a, int b){

// does some computations

}

// Now when i will call it as

a_function(3);

// Same error as you are getting will occur because the function expects 2 //argements and i am passing one.

Same will happen if i will call it as:

a_function (1,2,3);

Here i am passing one extra argument.

So, i will suggest to count the left function parameters and the arguments you are passing here in this function and you will find the mistake.
