Question

Tracie rolls a die numbered 1 to 6 three times. What is the probability that she will roll a 1, 2, and 3, in that order?
A.1/36
B.1/216
C.1/72
D.1/12

Answer 1

make a probablilty tree and figure it out

Answer 2

a probability tree?

Answer 3

sorry.... but im not that sure what that is. I'll google it though.

Answer 4

The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6 and so on for 3, 4, 5 and 6.
for the order to be 1,2 and 3,
the first time the probability of a 1 is 1/6
the second time the probability of a 2 is 1/6
the third time the probability of a 2 is 1/6
so multiply all the probabilities.
