Given : Five defective bulbs are accidently mixed with 20 good ones.
To find : probability distribution from this lot
Formula used :
Five defective bulbs are accidently mixed with 20 good ones.
Total number of bulbs = 25
X denote the number of defective bulbs drawn
X can draw the value 0 , 1 , 2 , 3 , 4.
since the number of bulbs drawn is 4, n = 4
The probability distribution table is as follows,
