Hello, let's have a look on the question.
00:02
So we know that summation of probability is always equal to 1.
00:05
So we can say that summation of all the probabilities, 0 .18 plus 0 .23 plus 0 .15, a and 0 .11 will be equal to 1.
00:19
So from here we can find out the value of a, that is 1 minus 0 .18, 0 .23, 0 .21, 0 .15, and 0 .15, and 0 .0 .0 .5, and 0.
00:30
So on calculating this value will be equal to 1 minus 0 .88, that is 0 .12.
00:37
So a is equal to 0 .12.
00:41
Now we need to compute probability x equal to 0.
00:45
So for the b part, probability x equal to 0, this will be equal to 0 .18.
00:55
For the c part, probability x is greater than equal to 3 is equal to probability that x equal to 3 x equal to 4 and probability x equal to 5 so this will be equal to 0 .15 plus 0 .12 plus 0 .11 that is 0 .38...
