Answer:

8 fruit total

1) orange probability: 4/8 = 1/2

pear probability after one fruit is taken out: 1/7

probability of getting one then the other without replacement: 1/2 x 1/7 = 1/14

2) orange: 1/2

apple: 3/7

pear: 1/6

probability of getting them in order without replacement: 1/2 x 3/7 x 1/6 = 1/28

3) apple: 3/8

orange: 4/7

apple: 2/6 = 1/3

probability of getting them in order without replacement: 3/8 x 4/7 x 1/3 = 1/14
