You cannot.
Probability is not a question or puzzle to be solved, it is a subject - a branch of mathematics. There are questions within the scope of the subject that may be solved.
You cannot solve probability since it is not a question! It is like asking how you can solve history!
The answer depends on that the problem is!
by doing what u think

First tell me a problem and might understand
There are many different problems and different ways for solving them.

Here is a website http://www.onlinemathlearning.com/theoretical-probability.html with relevant content on how you will solve for experimental and theoretical probability.
There are many ways one can go to learn how to solve probability problems. One can pick up a math tutorial book, look at tutorials online or enroll at a college.
P(A)=.35 P(B given A)=0.6 P(A and B)= ?
Count the total number of ways it can turn out. Count the number of ways that are the condition you're looking for. The probability of the outcome you're looking for is is the second number divided by the first number.
This is easiest to solve by working out the probability that no heads show and subtracting this from 1 to give the probability that at least one head shows: Assuming unbiased coins which won't land and stay on their edge, the probability of head = probability of tail = ½ → probability no heads = probability 5 tails = ½^5 = 1/32 → probability of at least one head = 1 - 1/32 = 31/32 = 0.96875 = 96.875 % = 96 7/8 %
