In this problem, we are given that there is a poisson distribution.
00:04
So we have the random variable x, and this is having poisson distribution, where the main value, let's represent that with lambda, this is given to us as 4.
00:14
So we have to first compute the probability that x is equal to 2.
00:19
So to get this, we will simply use this formula and plug in the values of the variables.
00:24
So doing that, we get this as 4 raised to 2 into e raised to minus 4 divided by 2 factorial.
00:30
And we see that this here, it simplifies to 0 .1465 as the result.
00:39
And in the next part, we have to compute the probability that x is less than 2.
00:45
So this will be the probability that x is equal to 0 plus probability that x is equal to 1...
