Probability that no zebras collide is 0.25

The zebras are represented as z1, z2 and z3.

Z1 to B, Z2 to C, and Z3 to A come first = (\frac{1}{2})^3

Following that, z1 to C, z2 to A, and z3 to B = (\frac{1}{2})^3

Consequently, the likelihood of no collision is 2×1/8 = 0.25.

<h3>What are the types of probability distributions ?</h3>

Discrete and continuous probability distributions are the two main categories in which probability distributions fall. There are numerous varieties of probability distributions within each category.

  • The number of favorable outcomes of an event divided by the total number of possible outcomes of an event can be used to calculate the probability of an event.
  • The likelihood of a sure or certain event is one.
  • The likelihood of an impossibility is 0 (0).
  • Every event has a probability between 0 and 1.

Joshua has a ladder that is 12 ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 11.
Nataliya [291]

Answer:

The ladder is not safe at this height. The height from ground to top of the ladder is < 11.6 ft for safety reasons and this can be determined by using trigonometry functions.

Step-by-step explanation:

The ladder is not safe at this height. The height from ground to top of the ladder is < 11.6 ft for safety reasons and this can be determined by using trigonometry functions.

Given :

Joshua has a ladder that is 12 ft long.

He wants to lean the ladder against a vertical wall so that the top of the ladder is 11.8 ft above the ground.

For safety reasons, he wants the angle the ladder makes with the ground to be no greater than 75°.

Check the angle that the ladder makes with the ground:

The ladder is safe when the angle the ladder makes with the ground to be no greater than 75° but  is  so, the ladder won't be safe.

To make the ladder safe, the height should not be 11.8ft.

The height from ground to top of the ladder is < 11.6 ft for safety reasons.

The price of an item has dropped to $39 today. Yesterday it was
Kobotan [32]

Answer:

40% decrease

Step-by-step explanation:

First, let's find the value decrease of the item from yesterday to today

$65 - $39 = $26

That means that $65 was 100% of the price and decreasing it by 26 gets us to 39

We need to find the percentage of 39 in 65

39/65 = 0.6 or 60%

If 39 is 60% of 65, then there was a 40% decrease form 100%

To check we can calculate the percentage of 26 in 65:

26/65 = 40%

There was a 40% decrease
