- c. 1/9 is the probability of getting the sum 5 in two throws of dice.
In two throws of a die, n(S) = (6 * 6) = 36.
Let E = event of getting a sum, n(E) ={(1, 4), (2, 3), (3, 2), (4, 1)}.
P(E)= n(E)/n(S)
=4/36

- Answer is 1/9(c)
throwing two dice sum 5 comes in (1,4) (2,3) (3,2) (4,1)
probability= 4/36 = 1/9
36 is no.of throws - 10 years agoHelpfull: Yes(3) No(0)
- (1,4) (2,3) (3,2) (4,1) are the possibilities on getting sum 5 on throwing 2 dice
Probability= 4/36 = 1/9
where 36 is the sample space - 10 years agoHelpfull: Yes(2) No(1)
