How to Find a Probability Calculator?
Probability of an event is defined as the ratio of favorable outcomes to the total number of outcomes. The probability of any event always lies between 0 and 1. To calculate the probability of any event we divide the favorable outcomes by the total number of outcomes.
What is the probability of selecting a black ball from a bag containing 4 yellow balls, 6 blue balls, 8 red balls, and 3 black balls?
Total number of possible outcomes = 21
Favorable outcomes = 3
Probability = 3/21
Probability = 1/7 = 0.14
Thus, the probability of selecting a black ball from the given bag is 1/7 or 0.14
