That means there is one 6, one 8, two 1's, and three 9's (total of 7).
P(8)=number of 8 cards/total number of cards=1/7
P(9)=3/7
P(6)=1/7
and although you didn't ask
P(2)=2/7
Answer by nerdybill(7384)  (Show Source):
You can put this solution on YOUR website! Probability = (number of favorable outcomes)/(total possible outcomes)
.
"number of favorable outcomes" = 5
Because out of the all the digits available, 5 of them are the numbers we want
.
"total possible outcomes" = 7
.
Probability = 5/7 = 0.714
OR,
71.4%
