Answer: 77/3 or 25 2/3
Step-by-step explanation:
1. Convert mixed numbers into improper fractions:
3 1/2 = 3*2+1/2 = 7/2
2 2/3 = 2*3+2/3 = 8/3
1 1/2 = 1*2+1 = 3/2
2. Calculate within parentheses
Multiply and divide from left to right
Add and subtract from left to right
Answer:
0.4546
Step-by-step explanation:
nCr = n!/(n-r)!r!
Number of ways of selecting the four defective voltage regulators from 12 = 12C4 = 12!/(12-4)!4! = 12!/8!4! = (12 *11*10*9)/(4*3*2*1)
12C4 = 495 ways
Number of ways of selecting 2 defectives from line 1 = 6C2 * 6C2
6C2 = 6!/(6-2)!2! = 6!/4!2! = (6*5)/(2*1) = 15
6C2 * 6C2 = 15*15 = 225 ways
Probability = Number of possible outcomes/ Number of total outcomes
Probability that exactly 2 of the defective regulators came from line 1 = 225/40.95 = 0.4546
