Answer: 0.8926

Step-by-step explanation:

Given : A shipment of 50 inexpensive digital watches, including 10 that are defective.

The probability that a digital watch is defective $: p=\dfrac{10}{50}=0.2$

Sample size : n=10

Also, they reject the whole shipment if 1 or more in the sample are found defective.

Using the binomial probability formula :

$P(x)=^nC_xp^x(1-p)^{n-x}$

Let x be the random variable that represents the number of defective watches.

The probability that the shipment will be rejected :-

$P(x\geq1)=1-P(0)\\\\=1-^{10}C_0(0.2)^0(0.8)^{10}\\\\=1-(0.8)^{10}=0.8926258176\approx0.8926$

Hence, the probability that the shipment will be rejected = 0.8926

Use the graph for this question:

Nadya [2.5K]

You basically need to find the slope of (2,-3) and (3,-1). Where x is 2, y is -3 and were x is 3, y is -1.
Slope is y2-y1/x2-x1
2 is your slope. So, the average rate of change from x=2 and x=3 is 2.
Hope I helped!
