A lottery game has balls numbered 1 through 19. If a ball is selected at random, what is the probability of obtaining an even numbered ball or the number 10 ball?

9/19

Step-by-step explanation:

Total number of ball=19

even ball=2,4,6,8,10,12,14,16,18

total number of even ball=9

total number of ball 10=1

Now, in probability, the probability of event A OR event B happening is the probability of event A plus the probability of event B minus the probability of both A AND B.

Let A be the event of drawing an even number.

Let B be the event of drawing a 10.

In this case then, we are drawing 1 ball only.

P(A)=9/19

P(B)=1/19

P(A and B)=1/19 (because 10 is both 10 AND an even number)

Then P(A or B)=P(A)+P(B)-P(A and B)

P(A or B)=9/19+1/19-1/21

P(A or B)=9/19

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
