A die is rolled twice. What is the probability of showing a 3 on the first roll and an even number on the second roll?

andreyandreev [35.5K]

Answer:

1/6 * 1/2 = 1/12

Step-by-step explanation:

1 number on a 6 sided die is 1 out of 6 (1/6) and an even number (2,4,6) on a 6 sided die is 3/6 or 1/2 (always simplify when multiplying fractions)

so 1 times 1 = 1 and 6 times 2 = 12 making it 1/12

A science fair poster is a rectangle 4 feet long and 3 feet wide. What is the area of the poster in square inches?

a_sh-v [17]

Answer:

Area of the poster is $1728$ square inches.

Step-by-step explanation:

First let's convert feet into inches.

1 feet = 12 inches

Length of the poster in inches:

$4$ feet = $4*12$ inches

= $48$ inches

Width of the poster in inches :

$3$ feet = $3*12$ inches

= $36$ inches

Area of a rectangle = Length * Width

Area of the poster = $48*36$

= $1728$ square inches
