The answer is 3.0 because you subtract answer
Answer:
0.778
Step-by-step explanation:
P(an Internet user posts photos that they have taken themselves/they post videos that they have taken themselves)=P(A/B)=?
According to conditional probability definition,
P(A/B)=P(A∩B)/P(B)
P(A)=0.54, P(B)=0.36, P(A or B)=0.62.
P(A or B)= P(A) +P(B) -P(A∩B)
P(A∩B)=P(A)+P(B)-P(A or B)
P(A∩B)=0.54+0.36-0.62
P(A∩B)=0.9-0.62
P(A∩B)=0.28.
P(A/B)=0.28/0.36
P(A/B)=0.778
So, the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves is 0.778.

Answer:
1. C
2. A
3. B
Step-by-step explanation:
1. 5x + 20 + 16 = 5x+36
2. 3x - 15 - x = 2x-15
3. 8x + 12 - 7x = x+12
