please help there both on probability using a spinner which is the spinner in the photos
The probability of the spinner landing on A is 3/8, the probability of the spinner not landing on C or E is 1/2
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
1) What is the probability of the spinner landing on A:
Total outcomes = 8
Total favourable = 3 (A repeated 3 times)
Probability = 3/8
2) Do you have an equal chance of landing on either B or E:
No, because the probability for B is 1/8 and the probability for E is 3/8
3) What is the probability of the spinner not landing on C or E:
P(not landing on C or E) = 4/8 = 1/2
4) Do you have an equal chance of landing on either B or C:
Yes, because both event has same probability = 1/8
5) What is the probability of the spinner not landing on A or E:
P(not landing on A or E) = 2/8 = 1/4
6) What is the probability of the spinner landing on C or E:
P(landing on C or E) = 4/8 = 1/2
7) What is the probability of the spinner not landing on A or B:
P(not landing on A or B) = 4/8 = 1/2
Similarly, we can find the rest of the probability.
Thus, the probability of the spinner landing on A is 3/8, the probability of the spinner not landing on C or E is 1/2

PLZ, QUICKLY IT IS HOMEWORK Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the other train travels at 80 mph. How long after they leave the station will they be 50 km apart?
Answer:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.
Step-by-step explanation:
The given is,
One train travels at an average speed of 80 km/hr
The other travels at an average speed of 70 km/hr
Step:1
Formula to calculate the distance traveled by two trains,
Distance traveled by two trains = (Rate of speed of train one +
Rate of speed of other train) × Time
From the given the above equation becomes,
Let, h = Time taken to each the distance
50 = ( 80 + 70 ) h
50 = (150) h
= 0.3333 hours
= ( 0.333 × 60 ) ( ∵ 1 hr = 60 minutes )
h = 20 minutes
Step:2
Check for solution,
From equation (1),
50 = ( 80+70 ) (0.3333)
50 = (150)(0.3333)
50 = 50
Result:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

Answer:
hi
Step-by-step explanation:
Both parallel sides are called bases. To find the area of a trapezoid we need to divide it into two triangles. Both triangles produced have the height h. The area of the trapezoid is the sum of the areas of the two triangles.
