Answer:
a. P(A) = P(B)
c. P(A) = 1 - P(B)
a and c are true . The rest are false.
Step-by-step explanation:
Two events A and B are said to be <u>equally likely </u> when one event is as likely to occur as the other. In other words each event should occur in equal number in repeated trials. For example when a fair coin is tossed the head is likely to appear as the tail, and the proportion of times each side is expected to appear is 1/2.
So when the events A= {1,3,4} B = {2,4,5} are equally likely then suppose their probability is 1/2.
a. P(A) = P(B) <u>True</u>
1/2= 1/2
b. P(A) = 2P(B) <u>False</u>
<u>1/2 is not equal to 1</u>
c. P(A) = 1 - P(B) <u> True</u>
1/2= 1-1/2= 1/2
d. P(A) + P(B) > 1 False
1/2 + 1/2 is not greater than 1
e. P(A) - P(B) < 0 False
1/2-1/2= 0 is not less than 0
f. P(A) - P(B) > 1 False
1/2-1/2= 0 is not greater than 1
Answer:
2 and 6
Step-by-step explanation:
Corresponding angles are the angles that occupy the same relative position at each intersection.
1 and 5
2 and 6
4 and 8
3 and 7
Answer: 7c ≤ 63
Ivan will buy at most 9 pounds of candy, which means that multiplying 9 by 7, the cost of the candy, will get your answer: 63. Plug these values into an inequality with a less than or equal to sign (≤) facing away from 63 and you're done!
The number of boys is:
30 - 12 = 18.
18 boys* (1/3)= 6 boys
There are 6 boys who study history.
6 students/ 30 students= 1/5.
1/5 of the students are boys who study history~
