Question

Two unbiased dice are rolled once. what is the probability to get 1) a doublet 2) a sum equal to 7​

Answer 1

Answer:

1) 1/6 2) 1 / 6

Step-by-step explanation:

Total numbers of outcomes = 36

1) favorable numbers of outcomes = 6

p (a. doublet ) = 6 / 36

= 1 / 6

2) favorable number of outcomes = 6

p ( a sum of 7 ) = 6 / 36

= 1 / 6

Answer 2

Answer:

1)1/6

2)

Step-by-step explanation:

1)no.of doublets = 6

total no.of outcomes = 36

So the probability of getting a doublet is :

No. Of doublets / total no. of outcomes =6/36=1/6

2)favourable outcomes = 6

totalno. of outcomes = 36

=6/36 = 1/6
