Answer:

5 / 12

11 / 36

Step-by-step explanation:

The sample space for 2 dice = 6² = 36

Number of outcomes where sum is less than 7 = 15

Probability = required outcome / Total possible outcomes

P(obtaining a sum less Than 7) = 15 / 36 = 5/12

Number of outcomes where Sum of individual outcome is less than 20 = 11

P(sum of individual outcome less than 20) = 11/ 36

John was 40 years old in 1995 while his father was 65.In what year was John exactly half his father's age?

babunello [35]

First, you would divide 65 by 2 and you would get 32.5. Then, You would subtract 32 from 40 to get 8. Finally you would subtract 8 by 1995 to get your answer for what year was john exactly half his fathers age and that year would be 1987. Your welcome :)
