Question

Find the probability of rolling a 7 when you toss two fair 6-sided dice and add the result from each die.

Answer 1

`(1)/(6)`

Explanation:

Total possible outcomes when you rolled the dices= 6*6=36

Outcome with sum as 7:

(1,6) (6,1)

(2,5) (5,2)

(3,4) (4,3)

N( outcomes with sum as 7)= 6

P(sum as 7):

`(n(outcomes \: with \: \: sum \: as \: 7))/(total \: outcome) \\ = (6)/(36) \\ = (1)/(6)`

Hope this helps...

Good luck on your assignment..
