If you send me the points I’ll do it in the comments
80 x 5 = 400
32 x 5 = 160
so you have about 160 <span>defective bulbs</span>
<span>Let X be the number of success in n trials. X has the binomial distribution with n = 4 trials and success probability p = 0.1666667 .</span>
The answer would be 5.79
Hope I helped :)
