Was there a chart with this?
From lea st to greatest it would be 6.200, 6.4, 6.532, and 6.6
Let lucy = l & neighbour= n
l = n +4
l + n= 14 years
substitute l with n +4
(n +4) + n = 14
2n +4 =14
n=5 years
l = n + 4 lets substitute n with 5
l = 5 + 4
lucy = 9 years
70% of 60 is just 60 multiplied by 0.7:

Then you add to get the total days:

So, in total, you have
102 days.
If we will roll a fair die then the outcomes wil be 1,2,3,4,5,6.
Hence, the total number of events= 6
3,4,5 and 6 are greater than 2.
So, there's 4 events which are greater than 2.
Now the formula to find the probability is:
probability=
=
=
So, the probability of getting greater than a 2 is 2/3.
