Answer:
P(A) = 0.49
Step-by-step explanation:
Given:
A and B are mutually exclusive events.
P(B) = 0.03
P(A or B) = 0.52
If two events A and B are mutually exclusive events, then there are no elements common in both the events. So, the probability of their intersection is 0.
Now, as per probability addition theorem:
P(A or B) = P(A) + P(B) + P(A and B)
For mutually exclusive events, P(A and B) = 0. So,
P(A or B) = P(A) + P(B) + 0
P(A or B) = P(A) + P(B)
Plug in the given values and solve for P(A). This gives,
0.52 = P(A) + 0.03
P(A) = 0.52 - 0.03
P(A) = 0.49
Therefore, the probability of occurrence of event A is P(A) = 0.49.

Answer:
The true proportion for the population would be between 0.386 and 0,398 (0.392±0.06) in 95% confidence level.
Step-by-step explanation:
Confidence interval for true population proportion can be computed as p±ME where
- p is the sample proportion (
) - ME is the margin of Error from the mean
and margin of error (ME) can be found using the formula
ME=
where
- z is the corresponding statistic in 95% confidence level (1.96)
- p is the sample proportion ( )
- N is the sample size (250)
Using the numbers
ME=
≈ 0.06
Then the true proportion for the population would be p±ME = 0.392±0.06 in 95% confidence level.
Answer:
444.6
Step-by-step explanation:
first find the area of the triangle: (9*7.6)/2 = 34.2
now multiply by depth: 34.2 * 13 = 444.6
volume of the figure = 444.6
