Question

Find the probability of finding the sum of 4 with two dice.

Answer 1

I mean rolling a 4
not the sum

Answer 2

probability of rolling a 4 with first throw is 1/6
probability of rolling another number on second throw = 5/6

- or the reverse could happen


this should help you


have you used tree diagrams?

Answer 3

i have not

1, 4
4, 1

3, 2

Answer 7

4 yes

Answer 8

and what is total outcomes in the sample space
the sample space is the set of all possible outcomes - 1,6 , 2,6 etc

Answer 9

yep so um 1234 i guess

Answer 10

?
no
sample space is 36 (6 * 6)

Answer 11
