Question

Suppose you just received a shipment of 6 televisions to of the televisions are defective if to to hella visions are randomly selected compute the probability that both televisions work what is a probability at least one of the televisions does not work

Answer 1

Solution: The question is missing information about the number of defective televisions.

Let's assume there are 2 defective televisions.

We are given that there are 6 televisions received.

The probability that both televisions work is:

$\boldsymbol{\frac{4}{6} \times \frac{3}{5}=0.4}$

What is a probability at least one of the televisions does not work?

$\boldsymbol{1-P(both-work)=1-0.4=0.6}$

Please note: Check the number of defectives if you have two defectives then you can use the above answers but if there are 3 defectives, then you need to make change accordingly.
