Question

a dice is thrown twice what is the probability that 5 will not come either time​

Answer 1

Answer:

25/36

Step-by-step explanation:

Throwing a die twice and throwing two dice simultaneously are treated as the same experiment.

Sample space =(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6), (4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6), (6,1),(6,2),(6,3),(6,4),(6,5),(6,6)

P(5 will not come up either time)= Number of times 5 does not show divided by total number of outcomes

P(5 will not come up either time)= 25/36
