A ball will be drawn from a bag containing 20 balls numbered 1 through 20 . If each ball is equally likely to be drawn, what is the probability that the number on the ball drawn will be even or less than 5 ?

7/10

Step-by-step explanation:

20 balls.

10 even, 10 odd.

4 numbers less than 5.

That is 14/20 --> 7/10

Most likely.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
