P(A) = 3/6 (3 out of all possible outcomes) = 1/3
P(B) = 3/6 = 1/3 again since possible odd numbers are 3 (1,3,5)
P(A/B) is basically 1/3 / 1/3
which is (3/3 = ) 1
Haven't worked with possibilities in ages so I'm not sure for the P(A/B) part! Sorry!
The hundredth is the second decimal place. You know the rounding rules are where you look at the previous place and if it's 5 or above the number place your rounding to goes up. So the answer is 423.41
I don't like these algebra problems which pretend to be geometry.
These are supplementary angles adding to 180 degrees; geometry done.
7x - 1 + 3x - 9 = 180
10 x = 190
x = 19
ABC=3x - 9 = 3(19) - 9 = 48
Answer 48°
