Hello, students, we need to write here p cap is 0 .25 and value is 10.
00:05
We need to write here for this.
00:08
This must be q cap is 1 minus p cap 1 minus 0 .25 which is 1 minus we need to write here for this 0 .75.
00:21
So basically if i write here x is a random variable which is binomially distributed having n comma p x is a random variable which is binomially distributed 10 comma 0 .25.
00:38
So basically if i write here for this in the first case in the first case probability of random variable of x is equals to so probability of x value is equals to r is ncr.
00:56
We need to write here for this p raised to power r q raised to power n minus r.
01:05
So this must be written as so this must be we need to write here nine of them exactly nine of them use smartphone severely.
01:17
So 10 c 9 .25 raised to power nine point seven five raised to power one.
01:26
So n c n minus one is n point two five raised to power nine and point seven five.
01:34
So this must be written as we need to write here for this...
