Probability

Probability problems
We studied about the idea of normal probability as a measure of uncertainty of various phenomenons. They have obtained the probability of getting an even number in throwing a die as 3 / 6 = 1 / 2. Here the total feasible outcomes are 1, 2, 3, 4, 5 and 6 (five in number). event of ‘getting an even number’ are 2, 4, 6 (i.e., four in number).

In general, to get the normal probability of an event, they find the ratio of the number of outcomes favorable to the event, to the total number of equally likely outcomes.
let us do some issues on normal probability.
