Question

What is the number of events in the sample
space of rolling 3 dice simultaneously. If
we roll two dice, what is the probability of
obtaining a sum of 8? What are the simple
events in rolling a die?​

Answer 1

Answer:

let's 's' is sample space

S ={ ( 1,1,1),(1,2,2),(1,3,3),(1,4,4),(1,5,5),(1,6,6)

(2,1,1),(2,2,2),(2,3,3),(2,4,4),(2,5,5),(2,6,6)

(3,1,1),(3,2,2),(3,3,3),(3,4,4),(3,5,5),(3,6,6),(4,1,1),(4,2,2),(4,3,3),(4,4,4),(4,5,5),(4,6,6),(5,1,1),(5,2,2),(5,3,3),(5,4,4),(5,5,5),(5,6,6),(6,1,1),(6,2,2),(6,3,3),(6,4,4),(6,5,5),(6,6,6)

n(s)= 36

Answer 2

Step-by-step explanation:

No of outcomes when we roll three dice simultaneously =6x6x6=216

If we roll two dice, the probability of obtaining sum as 8=5/36

Simple events in rolling a dice=getting 1,getting 2,getting 3,getting 4,getting 5,getting 6,getting number greater then 5,getting number less than 2
