If john pulls one marble out of the bag, what is the probability that it will not be red? that is, p (not red)?

Well maybe 100% because there is no numbers.

12 + 20 + 17 
= 49
So there are 49 marbles, and 12 of them are red
so that mean's there will be a 24.49% of picking a marble

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
