Answer 1

Answer:

please mark my answer as brainliest:

7/100, 1/19

1/20, 7/80

Step-by-step explanation:

firstly, figure out the total amount of students:

5+7+4+4=20

remember that dependant variables means you have to multiply the values

a)

figure out probability of choosing a green eyed student:

4/20

figure out probability of choosing a brown eyed student:

7/20

multiply values:

4/20 x 7/20 = 7/100

b)

probability of choosing a blue eyed student:

5/20 = 1/4

probability of choosing another blue eyed student:

4/19 (bc theres 1 less)

multiply:

1/4 x 4/19= 1/19

PART 2

a)

probability of choosing a hazel eyed student:

4/20

probability of choosing a blue eyed student:

5/20 = 1/4

multiply:

4/20 x 1/4 = 4/80= 1/20

b)

probability of choosing a brown eyed student:

7/20

probability of choosing a blue eyed student:

5/20 = 1/4

multiply:

7/20 x 1/4 = 7/80
