Answer:

$\large\boxed{\large\boxed{10/21}}$

Explanation:

There are only two mutually exclusive possibilities for each complex electronic system: being defective or being not defective:

Number of complex electronic systems: 7
Nmber of defective systems: 2
Number of not defective systems: 5

Probability that no defective systems are found in the sample is the equal to the probability of selecting them consecutively without replacement and finding each one is not defective:

Porbability the first is not defective × probability the second is not defective

5/7 × 4/6 = 20/42 = 10/21

slavikrds [6]

Step-by-step explanation:

Using R, I used the following code to create a histogram:

bowling.scores <- c(87, 104, 79, 94, 117, 82, 72, 116, 105, 95, 88, 93, 109, 119, 75,

103, 112, 97, 73, 85, 91, 86, 102, 99, 106, 84, 98, 83, 81, 96, 92)

data.frame(bowling.scores)

ggplot(data.frame(bowling.scores), aes(x=bowling.scores)) +

xlim(c(70, 120)) +

scale_y_continuous(breaks = seq(0, 10, by=1), "Frequency") +

geom_histogram(breaks=seq(70, 120, by=10), color="black", fill="grey60") +

labs(title="Histogram of Bowling Scores", x="Bowling Scores", y="Frequency")
