Answer:
1) factor pairs- 1*328, 2*164, 4*82, 8*41
1,2,4,8,41,82,164,328
2) 2^3, 41
not a prime number
5(9 + 7) = 5 x 9 + 5 x 7 = 45 + 35
I think the answer for your question is B
P(picking one defective) = 3/10
P(picking a 2nd defective) = 2/9
P(1 and 2 defective) = 3/10 x 2/9 = 6/90 = 0.066
Second method using combination:
³C₂ / ¹⁰C₂ = 1/15 = 0.066
Answer: 80
Step-by-step explanation: multiple b(3) with everything its next to, then add it all up
