Question

two dice are rolled once what is the probability of getting a doublet and sum equals to 7 ​

Answer 1

Answer:

doublet means same number on both the dice.

a doublet

there are 6 possibilty of doublet

total number of outcome = 36

probability = possible outcomes/total outcome

= 6/36 = 1/6

sum is equal to 7

there are 6 possibilty of the same.

probability = favourable outcome/total outcome

= 6/36 = 1/6

hope this will help you

Answer 2

Answer:

two dice are rolled together

total outcome =36

doublet =(1,1)(2,2)(3,3)(4,4)(5,5)(6,6)

probability= favorable outcome/total outcome=6/36=1/6

sum of 7 =(1,6)(4,3)(6,1)(4,3)(5,2)(2,5)

probability=favorable outcome/total outcome=6/36=1/6...

hope this helps!!
