In this question, we have been given that 10 coins are tossed and we need to find the mean, variance and standard deviation for the number of heads.
00:08
So this is a binomial experiment since getting head is basically the success and getting tail is basically considered as failure.
00:17
So, n will be considered as the number of trials and then the value of p will be here equals to half because there is 1 divided with 2 chance of getting a head.
00:28
So it is basically the value of success.
00:31
And here the value of failure that is q will be equal to 1 minus p and that is equal to 1 divided with 2.
00:38
So p value is also the value of getting a head and q value is also the value of getting a tail.
00:45
So here we can say that mean value will be here equals to n times p and that can be here written as 10 times p value is half.
00:55
So it is here equals to 5.
00:56
So, we have find out the main value...
