Wewaii [24]

Answer:

a)%85,5

b)%92,2

Step-by-step explanation:

a) To determine the probability of getting a hand with at least one face, we need to calculate the probability of the hand without any face firstly.

(36/52)*(35/51)*(34/50)*(33/49)*(32/48)=0,145

Then, we need to deduct this value from the probability 1

1-0,145=0,855

The probability of the hand with at least one face is %85,5.

b)To determine the probability of a hand with at least one ace and face we will track the same road again.

(32/52)*(31/51)*(30/50)*(29/49)*(28/48)=0,0775

Then, we need to deduct this value from the probability 1

1-0,0775=0,922

The probability of the hand with at least one ace and one face is %92,2.

1. Sam walks 3/8 km to school. After school, he walks another (x+1)/3 km to get to work. What simplified rational expression des
Brilliant_brown [7]

Answer:

The answer to your question is (17 + 8x)/24

Step-by-step explanation:

Data

First distance = 3/8 km

second distance = (x + 1)/3 km

Process

1.- Sum both distances

                    3/8 + (x + 1)/3

- Find the Least common factor

                    8   3   2

                    4   3   2

                    2   3   2

                     1   3   3

                          1

LCF = 2x 2 x 2 x 3 = 24

- Sum the fractions

                  3/8 + (x + 1)/3 = (9 + 8(x + 1)) / 24

-Simplification                                          

                                         = (9 + 8x + 8) / 24

-Result

                                         = (17 + 8x)/24
