Solve p(2)=5/(5-2)!2!=

$$p ( 2 ) = \frac { 5 } { ( 5 - 2 ) ! 2 ! } =$$

Evaluate

$$\frac{5}{12}\approx 0.416666667$$

Solution Steps

Subtract 2 from 5 to get 3.

$$\frac{5}{3!\times 2!}$$

The factorial of 3 is 6.

$$\frac{5}{6\times 2!}$$

The factorial of 2 is 2.

$$\frac{5}{6\times 2}$$

Multiply 6 and 2 to get 12.

$$\frac{5}{12}$$

Factor

$$\frac{5}{2 ^ {2} \cdot 3} = 0.4166666666666667$$
