Question

two dice are rollrd simultaneously and counts are added i) complete the table​

Answer 1

Two dice, one blue and one grey, are thrown at the same time. Complete the following table: Event: Sum on two dice, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 Probability, , , , , , , , , , , From the above table a student argues that there are 11 possible outcomes 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. Therefore, each of them has a probability 111 . Do you agree with this argument?

Answer 2

Step-by-step explanation:

Total number of possible events or outcomes for 2 dice = 36

 

Event:

Sum on 2 dice                               

Probability      Reason :

possible events21/36 32/361+2, 2+1 => 2

events 43/361+3, 2+2, 3+1 => 3

events54/361+4,2+3,4+1,3+2=>4

events65/361+5,3+3,2+4,5+1,4+2=>5

events76/361+6,2+5,3+4,4+3,5+2,6+1=>6

events85/362+6,3+5,4+4,6+2,5+3=>5
