1. Probability Theory studies the mathematical chances of something happening, based on real and numerical data, such as: rolls of dice and coins, up to the chance of errors in research. When rolling an unbiased die, we consider “A” the
Choose the correct alternative for these two events.
A) The union of the two events is called an impossible event.
B) The intersection of the two events is called a certain event.
C) A and B are complementary events but not mutually exclusive.
D) A and B are mutually exclusive events but are not complementary.
E) A and B are complementary and mutually exclusive events.
2. There are, by hypothesis, infinite number bases, but in computing we use hexadecimal, octal and binary bases. The octal base was once widely used, but today the hexadecimal system is the most used as an alternative to binary.
Check the alternative that shows the correct value of the conversion of the following number in hexadecimal A02C3D(16) to octal.
