Step-by-step explanation:
1. P(light OR domestic) = P(light) + P(domestic) − P(light AND domestic)
P(light OR domestic) = 0.62 + 0.70 − 0.55
P(light OR domestic) = 0.77
2. P(light AND not domestic) = P(light) − P(light AND domestic)
P(light AND not domestic) = 0.62 − 0.55
P(light AND not domestic) = 0.07
3. P(light GIVEN not domestic) = P(light AND not domestic) / P(not domestic)
P(light GIVEN not domestic) = 0.07 / (1 − 0.70)
P(light GIVEN not domestic) = 0.233
4. Two events are independent if P(A) × P(B) = P(A and B).
P(light) × P(domestic) = 0.62 × 0.70 = 0.434
P(light AND domestic) = 0.55
Therefore, the type and location are not independent.
6:18 students in Debra's class own a cellphone. Because there are 24 people in total. Minus the people who already own cellphones. Leaving 18 without cellphones. The ratio is people who have cellphones to people who do not.
24-6=18. Thus, the ratio would be 6:18
Answer:
4
Step-by-step explanation:
A+B+C=180, C=90. A+B=90. A=90-B. Cos(A) = sin(90-A)
Answer:1 and 1/4
Step-by-step explanation:
Okay, let's see the given: 20/16
So, we can take out 16 from the top to make it 1 4/16
Now, we can simplify that by dividing the top and bottom by 2: 1 2/8
We can simplify that again to get 1 1/4
So the answer is 1 and 1/4
Answer:
A
