Question

Two dice blue and grey are thrown at the same time what is the probability that the sum of the 2 numbers appearing on the dice are (i)8 (i)less than or equal to 12

Answer 1

Answer:

i)5/36 ii)1

Step-by-step explanation:

i) for addition to be 8 ,  the favorable outcomes are= (2,6) (3,5) (4,4) (5,3) (6,2)

total no of outcomes are 36

so 5no of favorable outcomes) / 36

ii) total no of outcomes = 36

favorable outcomes are 36,(because at any values, the addition of the 2 numbers will always be = or lesser than 12 eg. 6,6 .. 6+6 = 12

hence the even is a sure event(36/36)

hence 1
