Question

At a game booth, a student gets a box of candy as the prize for winning a game. The boxes come in four colors; white, red, green, and blue. There are 8 boxes of each color. All of the boxes are equally likely to be given away as prizes. Which expression shows the probability of the first winner receiving a white box and the second winner also receiving a box of the same color?

A: (8/32)•(8/31)
B: (8/32)+(8/31)
C: (8/32)+(7/31)
D: (8/32)+(7/31)

Answer 1

I think its C

Explanation:

There is no 'and' to indicate that it is multiplication

Answer 2

there is no correct answer ,

the answer should be (8/32)•(7/31)

Explanation:

P(first white box)=8/32

P(second white box)=(8-1)/(32-1)=7/31

so

P( both white box)= (8/32)X(7/31)
