Answer:
THE PROCESS BY WHICH GREEN PLANTS TURN CARBON DIOXIDE AND WATER INTO FOOD USING ENERGY FROM SUNLIGHT
Answer:
5. 1/3
6. 5/9
7. 7/9
8. 1/2
9. 2/5
10. 3/10
Step-by-step explanation:
B. Number of green clips = 4
Number of blue paper clips = 6
Number of red paper clips = 8
5. P( getting a blue clip ) = 6/(6+4+8)
= 6/18 = 1/3
6. P( getting a paper clip that is not red ) = 4+6/(6+4+8)
= 10/18 = 5/9
7. P( getting a paper clip that is blue or red ) = 6+8/(6+4+8)
= 14/18 = 7/9
C. Total number of balls = 20
Number of even balls = 10
Number of odd balls = 10
8. P( getting an even number ball ) = 10/20 = 1/2
9. Prime numbers between 1 and 20 are 2, 3, 5, 7, 11, 13, 17, 19
P( getting a prime number ball ) = 8/20 = 2/5
10. Numbers divisible by 3 between 1 and 20 are 3, 6, 9, 12, 15, 18
P( getting a number divisible by 3 ) = 6/20 = 3/10
