A bag contains 30 lottery balls numbered 1-30 a ball is selected, not replaced,then another is drawn.find each probability
Valentin [98]
The probability of the first event with x possible outcomes is equal to x/30. Also, the probability of the second event with y possible outcomes is y/29.

(1) P of 2 digit number, 21/30
      P that the number is 4 is 1/29
Multiplying both probabilities will give us 7/290

(2) P that number is 19 is 1/30
      P that the number is multiple by 4 is 6/29
The answer is 1/145

(3) P that number is 24 is 1/30
      P that number is less than 15 is 14/29
The answer should be 7/435.

(4) P that number 1st number is perfect square is 5/30
   P that second number is perfect square is 4/29.
The answer is 2/87.

svp [43]
For an inscribed quadrilateral, opposite angles add up to 180 degrees. In this case, if we are looking for the measure of angle D, we can use the fact that angles I & D add up to 180 degrees. Since angle I = 117:
117 + D = 180
D = 63 degrees
