POSSIBLE POINTS: 4.17 Mario's parents tell him he doesn't have to do the dishes if he can flip heads on a fair coin and roll an even number on a fair six-sided die. What is the probability that Mario can get out of doing the dishes ? In other words, P(heads and even number) = ?

P(heads and even number) = 1/4

Step-by-step explanation:

Given:

Coin tossed for head

Dies role for Even number

Find:

P(heads and even number)

Computation:

P(heads) = 1/2

P(even number) = 3/6

P(even number) = 1/2

P(heads and even number) = P(heads) × P(even number)

P(heads and even number) = 1/2 × 1/2

P(heads and even number) = 1/4

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
