Question

A bag has 8 number tiles numbered one through eight. You draw a number tile, replace the tile and draw a second tile. What is the probability that you will draw a 6 and then a 7? Only answer if you answer is 100% correct.

A. 1/64
B. 1/56
C. 1/16
D. 1/8

Answer 1

the answer is D because they take a tile out which makes it 7 tiles in the bag but then they put it back which makes the bag have 8 tiles in it again.

Answer 2

Total number tiles = 8
Number of 6 = 1
Number of 7 = 1

P(a 6 and then a 7) = (1/8)(1/8) = 1/64 (Answer A)
