Answer:
The required probability is 0.09875
Step-by-step explanation:
From the given information;
the probability of repairing the telephones = 0.70
the probability of the replaced = 0.30
Suppose we consider Mto denotes the telephone that is submitted for service while under warranty and must be replaced.
Then;
p = P(S) = P(replaced | submitted) P(submitted)
= 0.30 × 0.20
= 0.06
Now, the probability that exactly two will end up being replaced under warranty given that it assumes a binomial distribution where n = 10 and p = 0.06



11. # of hot dogs= 2s
12. The amount of materials= 4w
13. y= 1.10m + 2
14. t= 0.08d
15. c= 0.25p
16. b= 0.05t + 49
Length (L): 4w - 5
width (w): w
Perimeter (P) = 2L + 2w
140 = 2(4w - 5) + 2(w)
140 = 8w - 10 + 2w
140 = 10w - 10
150 = 10w
15 = w
Length (L): 4w - 5 = 4(15) - 5 = 60 - 5 = 55
Answer: width= 15meters, length=55 meters
