Question

two dice are rolled find the probability that the sum is a) equal to 1 b) equal to 4 c) less than 13

Answer 1

two dice are thrown here n
$n(s) = 36$
a) the sum is equal to 1 is zero because they starts with (1,1) .... likewise . other than in the dice we are not having zero.
b) the sum is equal to 4 the possible outcomes are (1,3),(2,2),(3,1) therefore n( b) = 3/36 = 1/12
c) their sum is less than 13. here the total sample space will come . n(c)= 36/36 = 1.

Answer 2

Step-by-step explanation:

two dice thrown is =36

a) answer is =0

b)answer is = (3/36)

=(1/12)

c) answer is =(36/36)

= 1
