Answer:
Mixed probabilty
Step-by-step explanation:
What is the probability that the first and second ball chosen are both targets, that is, X1 = 1 X2 = 2?
For this we must study the simple probability of each, for example for the target in that event is 5/13. However for the second chosen but also white in the second event where there is already a total of 12 balls is 4/12.
Thus
In this way is generated for all probabilities
b) In the same way analogous to the past example we can perform all cases of combinations, therefore it would be so

A right triangle is a special type of triangle where one of the angles makes a right angle or has 90 degrees. The longest side is called as the hypotenuse. The sides can be related by the Pythagorean theorem but it would not be useful here since we are given an angle. Instead, we find other relations. The sides and the angles can also be related by trigonometric functions. For this case we use cosine given that the leg given is adjacent to the angle. We calculate as follows:
cosine 51 = 12 units / hypotenuse
hypotenuse = 19.07 units
The length of the hypotenuse would be about 19.07 units.
