A national standard requires that public bridges over 20 feet in length must be inspected and rated every 2 years. The rating scale ranges from 0 (poorest rating) to 9 (highest rating). A group of engineers used a probabilistic model to forecast the inspection ratings of all major bridges in a city. For the year 2020, the engineers […]
In a random sample of 100 adults, we found that 36% access the Internet at work; 44% access the Internet at home; and 20% access the Internet at both home and work. Find the probability that a randomly selected person from this sample access the Internet only at work? only at home? at work OR home? at […]

One method of increasing patients’ awareness of the problem is for physicians to provide patient medication instruction (PMI) sheets. A local medical survey, however, has found […]
If x is a binomial random variable, use the binomial probability table to find the probabilities below. a. P(x=3) for n=10, p=0.2 b. P(x≤4) for n=15, p=0.3 c. P(x>1) for n=5, p=0.5 d. P(x<17) for n=25, p=0.9 e. P(x≥14) for n=20, p=0.9 f. P(x=3) for n=20, p=0.1 Find: P (x=3) P (x≤4) P (x>1) P(x<17) P(x≥14) P (x= 3) Looking […]
