Anumber cube with faces numbered 1 through 6 is rolled and a coin is tossed. what is the probability that the number cube will show a number greater than 4 and the coin will land with tails up? a. 1/12 b. 1/6 c. 2/5 d. 5/6

b 1/6

Step-by-step explanation:

the probability of the dice rolling on five or six is 2 out of 6. the probability that the coin will

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
