Answer: 0.9972
Step-by-step explanation:
Given : The proportion of Americans believe that texting while driving should be outlawed : p= 0.97
Sample size : n= 10
Using Binomial distribution , the probability of getting success in x trials is given by:-
, where p is probability of success in each trial and n is sample size.
Then, the probability that at least 8 say that they believe texting while driving should be outlawed will be :_
Hence, the required probability = 0.9972

Answer:
total cost for Samantha to get her degree = $5,128.2
Step-by-step explanation:
Number of trimesters per year = 3
Number of years = 4
∴ Total number of trimesters throughout college = 3 × 4 = 12 trimesters
Tuition per trimester = $2.350
Total tuition (12 trimesters) = 2.350 × 12 = $28.2
cost of books per trimester = $425
cost of books throughout college (12 trimesters) = 425 × 12 = $5,100
total cost for Samantha to get her degree = total cost of tuition + total cost of books
total cost for Samantha to get her degree = 28.2 + 5,100
total cost for Samantha to get her degree = $5,128.2
