wat is probability
probability is the chance that something will happen. for example, there is a spinner that is divided into 6 equal parts. 2 are blue, 2 are green, 1 is yellow, and 1 is red. the probability that the spinner will land on blue is 2 out of 6.
The study of probability helps us figure out the likelihood of something happening. For instance, when you roll a dice, you might ask how likely you are to roll a 4.Since there are 6 numbers on a dice and only 1 number 4 the probability would be 1 out of 6.
The probability of the occurrence of an event can be expressed as a fraction or a decimal from 0 to 1.
So 1 out of 6 can be written as:
1/6 - fraction
0.16666-> - decimal
a coin is tossed once. the probabily of getting heads is tails is
