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
<em>remember that dependant variables means you have to multiply the values</em>
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 = <u>7/100</u>
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
Set up a proportion.
25/5 = x/8
Cross multiply
25*8 = 200
200/5 = x
x= 40
