Probability
Science students will always encounter situations where they will be required to determine the likelihood of an event occurring or not occurring. Being an important concept, especially in mathematics, all students must learn and master the basics of this concept. Therefore, probability refers to the possibility that an event will occur.
Probabilities range from 0 to 1. The probability (P) of an event (E) happening P(E) is given as;
0 ≤ P(E) ≤ 1
The probability that something will happen is calculated as:
Probability=the number of ways an event can occur/the total number of possible outcomes
