Complete question:
Calculate each probability given that P(A) = 0.2, P(B) = 0.8, and A & B are independent.
a) compute P(A and B)
b) If P(A|B) = 0.7, compute P(A and B).
Answer:
(a) P(A and B) = 0.16
(b) P(A and B) = 0.56
Step-by-step explanation:
Two events are independent if occurrence of one event does not affect possibility of occurrence of another.
(a) if A and B are independent, then P(A and B) = P(A) x P(B)
= 0.2 x 0.8
= 0.16
(b) If P(A|B) = 0.7, compute P(A and B)
Considering the notations of independent events,
= 0.7 x 0.8
= 0.56
Answer:
1. 3/5 c
2. 7 c
3. 2/5 b
4. $3.24 c
5. -3.2 b
Step-by-step explanation:
1.
2/5 + 1/5 = 3/5
2.
a negative + a negative = a positive
2+5 = 7
3.
terminating means the decimal ends. When u divide a & c they keep on going but 2/5 ends
4.
divide 16.8 by 5.19 = 3.23 round up so 3.24
5.
multiply the two together to get the answer
Answer:
Daniel
Step-by-step explanation:
Daniel ran 5000/40=500=4=125 meters in 1 minutes
Andy ran 4550/37=122.9729... some less than 123 meters in second
Daniel was faster than Andy
Answer:
The answer is not provided in there but the answer is -2(4x-13)
7/8. 8×5=40. 35/40
9/10. 10×4=40. 36/40
