You pick only one letter, so the possible outcomes are:
A,C,O,M,D,T, I, N
if you need to probability of each outcome:
A: 2/13 (there are 2 As and a total of 13 letters)
C: 2/13
O: 3/13
ans so on.
use your calculator to change each fraction to a decimal if needed.
Let :
T = Theresa age
H = her brother
We know :
T = H - 14
T + H = 35
Substitute T
H -14 + H = 35
2H - 14 = 35
2H = 49
H = 49/2 = 24.5
Since we know H = 24.5 we then can substitute it to either equation.
T = H - 14
T = 24.5 - 14
T = 10.5
Theresa is 10.5 years old
Her brother is 24.5 years old
