Here the number of trials n equal to 4 and it follows a binomial distribution.
00:05
Therefore the probability of success we are denoting it as p and the probability of failure we are denoting it as q which is equal to 1 minus p.
00:17
Okay.
00:18
So here the variable x represents the number of successes in four trials and based on this the total number of outcomes equal to 2 power 4 which is.
00:30
Equal to 16 so now what we are going to do is we are forming the table with outcome x and probability so the outcome possible outcomes will be four success and in this case x equal to 4 the probability is p power 4 next we will get yes yes yes if the possible number of success 3 and probabilities p power 3 multiplied by 1 minus p next one s, f, yes, yes, yes.
01:04
Here also, success three and the probability is p cubed multiplied by 1 minus p.
01:10
Next one, yes, yes, f s, f s, f, f, f, x, f, x equal to 3 and probability remains the same, p cubed into 1 minus p.
01:19
The next one is f, s, yes, yes, yes, three times only...
