This is because the risks associated with a second-hand car are higher. This is due to the fact that that they are more likely to break down than new cars.

Two non-simultaneous events have an equal likelihood of occurring (50%). If the events are independent of each other, what is the probability that they will both occur?

Answers

Answer: Probability that they will both occur is 25%.

Step-by-step explanation:

Since we have given that

There are two non simultaneous events.

Probability of each event = 50%

Since both are independent to each other.

Let A and B be two events.

We need to find the probability that they will both occur i..e P(A∩B).

As we know the rule of independence of events:

$P(A\cap B)=P(A).P(B)\n\nP(A\cap B)=0.5* 0.5\n\nP(A\cap B)=0.25\n\nP(A\cap B)=25\%\n$

Hence, Probability that they will both occur is 25%.

25% should be the answer, let me kno if its correct

A restaurant requires 4 1/2 ounces of butter for every bowl of curry it makes. In an hour an average of 2 1/2 bowls of curry is served.How many ounces of butter are required in 1 1/2 hours?

ounces

Enter a number like 212or 52.

Answers

1 Ounce of Butter = B

Bowl of Curry = C

1 Hour = H

----------------

A restaurant requires 4 + 1/2 ounces of butter for every bowl of curry it makes...

C = 9/2 * B

In an hour, an average of 2 + 1/2 bowls of curry is served...

H = 5/2 * C

... Which means that: H = 5/2 * 9/2 * B

... So: H = 45/4 * B

The question was: How many ounces of butter are required in 1 + 1/2 hours?

Here is the answer:

3/2 * H = 3/2 * 45/4 * B

3/2 * H = 135/8 * B

In words, 16 + 7/8 ounces of butter would be required over a period of 1 + 1/2 hours.

If a = -2, b= -5, and c = -6, then a - b + c =

(Hint: NOT -1 or -13)
