Probability Definition in Math-

  • Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
  • Four perspectives on probability are commonly used: Classical, Empirical, Subjective, and Axiomatic.
  • For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail). We write P(heads) = ½ .

  • It’s simple. there are 7 digits, so that would mean you start with 0,000,000 and end with 9,999,999.
  • If the highest digit is 9,999,999 and you add a 1 more to it, you have a total of 10M combinations.

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs ​$70. A season ski pass costs ​$300. The
MatroZZZ [7]

The number of days when the season pass would be less expensive than the daily pass is 5 days.

<h3>How many days would the season pass be less expensive?</h3>

The equation that represents the total cost of skiing with the daily pass : (daily pass x number of days) + (cost of renting skis x number of days)

$70d + $20d = $90d

The equation that represents the total cost of skiing with the seasonal pass : cost of season pass + (cost of renting skis x number of days)

$300 + $20d

When the season pass becomes less expensive, the inequality equation is:

Daily pass > season pass

$90d > $300 + $20d

In order to determine the value of d, take the following steps:

Combine and add similar terms: $90d - $20d > $300

70d > $300

Divide both sides by 70 d > $300 / 70

d > 4.3 days

Approximately 5 days.

Nick's dad wanted to measure the length of his backyard and asked Nick to do this with his footsteps. Since it was winter, they
Lerok [7]

Answer:

2244 cm

Step-by-step explanation:

The first first thing we must do is find the LCM of the following numbers

(51; 68) = 204.

This means that the first time they coincide is at 204.

Now, since his steps always coincide after 204

In Nick's case

Nick's 204 ÷ 51 = 4th step

and in the case of the father

204 ÷ 68 of his father = 3rd step.

Which means that in the 204 cm distance, there will be a total of 6 foot steps, except in the first 204 cm when your "initial" step is counted.

Replacing these values we have that the total distance will be:

67-1 (initial step) / (6 * 204) = 2244 cm
