Answer:

Therefore the required probability is 0.15.

Step-by-step explanation:

Poisson distribution:

The Poisson distribution is the number of an event is occur within a time period.

$P(X=x)=\frac{e^{-\mu}\mu^x}{x!}$

μ= The mean

x= event.

In Poisson distribution , the average rate event per time period is constant.

12% defective parts is produced by one of the machines of the time.

μ= (12%×7)= 0.84

x= the number of defective product =2

$P(X=2)=\frac{e^{-0.84}(0.84)^2}{2!}$

=0.15

Therefore the required probability is 0.15.

joja [24]

Answer:

0.1

Step-by-step explanation:

chance of pulling out a blue marble can be described as 8 equally probable outcomes (blue marbles) out of 20 equally probable outcomes (all marbles).

Similarly, the chance of pulling out a green marble is 5 out of 20.

In total, we have 8*5 (combinations of blue then green) outcomes out of 20*20 (any two marbles):

8*5 / (20*20) = 40 / 400 = 1/10 = 0.1
