Jonathan draws a ticket from a box to select the door prize winners at a party. The tickets are numbered from 1 to 25. What is the expected value that the tickets drawn will have numbers less than 5 if he draws tickets 40 tickets

6

Step-by-step explanation:

Given that there are tickets in the draw which are numbered from 1 to 25.

Probability of an event E is given by the formula:

Probability of each number can be found out as:

Number of favorable cases for each number is 1 and total number of cases here is equal to the total number of tickets i.e. 25.

Now, the numbers less than 5 mean 1, 2, 3 and 4.

Therefore, 4 number of favorable cases.

Now, it is given that 40 tickets are drawn.

Number of times, the numbers less than 5 are expected:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
