Chapter 9, Problem 3TYS

(a)

To determine

To graph: The probability distribution:

$x$	$1$	$2$	$3$	$4$
$P\left(x\right)$	$\frac{3}{16}$	$\frac{7}{16}$	$\frac{1}{16}$	$\frac{5}{16}$

and calculate the probabilities $P\left(x<3\right)$.

(b)

To determine

To graph: The probability distribution:

$x$	$1$	$2$	$3$	$4$
$P\left(x\right)$	$\frac{3}{16}$	$\frac{7}{16}$	$\frac{1}{16}$	$\frac{5}{16}$

and calculate the probabilities $P\left(x\ge 2\right)$.
