Suppose you just received a shipment of eleven televisions. Three of the televisions are defective. If two televisions are rando
salantis [7]

Answer:  The probability that both televisions work : 0.5329

The  probability at least one of the two televisions does not​ work : 0.4671

Step-by-step explanation:

Given : The total number of television : 11

The number of defective television : 3

The probability that the television is defective : p=\dfrac{3}{11}\approx0.27

Binomial distribution formula :-

P(x)=^nC_xp^x(1-p)^{n-x}, where P(X) is the probability of getting success in x trials, p is the probability of success and n is the total trials.

If two televisions are randomly​ selected, then the probability that both televisions work:

P(0)=^2C_0(0.27)^0(1-0.27)^{2-0}=(1)(0.73)^2=0.5329

The probability at least one of the two televisions does not​ work :

P(X\geq1)=1-P(0)=1-0.5329=0.4671
