Pairs whose sum is 8:
2 + 6, 3 + 5, 4 + 4, 5 + 3, 6 + 2 ( there are 5 pairs )
Pairs when one die is 5: 3 + 5, 5 + 3 ( 2 pairs )
P ( A ) = 2 / 5 = 0.4
Answer: The probability that one die resulted in a 5 given that a sum is 8 is 0.4 .

Answer:
260%
Step-by-step explanation:
To solve how much the percentage increase cost of Jo's car insurance is, we first need to list down our variables.
1st year = £245
2nd year = £883
First off, we need to find the difference of the two.
Increase = £883 - £245
Increase = £638
Now to find the percentage increase, we take our increase and divide it by our 1st year's payment and multiply it by 100.
Percentage increase = 
Percentage increase = 
Percentage increase = 260%
