Explanation Given: n = 4 x = 2 p = 1 3 Approach: The expanded expression of C ( n , x ) is given as; C ( n , x ) = n ! x ! ( n − x ) ! If p is the probability of success of an event and q is the probability of failure of an event. Then, the relationship between p and q is given as: q = 1 − p Calculation: Calculate the value of q . Substitute 1 3 for p in the expression for q . q = 1 − 1 3 = 2 3 Consider the given function. C ( n , x ) p x q n − x Write it in expanded form. C ( n , x ) p x q n − x = n ! x ! ( n − x ) ! p x q n − x Substitute 4 for n , 2 for x , 1 3 for p and 2 3 for p in the above expression
