Suppose there are 30 people at a party. do you think any two share the same birthday? let's use the random-number table to simulate the birthdays of the 30 people at the party. ignoring leap year, let's assume that the year has 365 days. number the days, with 1 representing january 1, 2 representing january 2, and so forth, with 365 representing december 31. draw a random sample of 30 days (with replacement). these days represent the birthdays of the people at the party. would you expect any two of the birthdays to be the same?

Then the calculation for 30 people would be:
(365!/365-30!)/(365^(30)= (365!/335!)/ 365^30= 29.4%
Then the probability of at least two person have same birthday would be: 100%-29.4%= 70.6%
Ответ:
The probability that at least 2 people have the same birthday is 29.37%
Further explanationProbability is the likelihood of an event occurring. Probability is the number of ways of achieving success. Probability is also the total number of possible outcomes.
Suppose there are 30 people at a party. Do you think any two share the same birthday?
Let's use the random-number table to simulate the birthdays of the 30 people at the party, ignoring leap year.
Let's assume that the year has 365 days. number the days, with 1 representing January 1, 2 representing January 2, and so forth, with 365 representing December 31.
Draw a random sample of 30 days (with replacement). These days represent the birthdays of the people at the party. Would you expect any two of the birthdays to be the same?
For 30 people
365! = 365*364*363*...336
So
The probability that at least 2 people have the same birthday is 29.37%
