The probability that the computer is an all-in-one machine is 10%
According to the statement
we have given that the 30% of the computers in stock are laptops, 60% are traditional desktops, and 10% are all-in-one touch screen machines.
And we have to find the probability that the computer is an all-in-one machine.
So, For this purpose, we know that the
The probability is the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
So, According to the statement
The computers in stock are laptops are 0.3
The computers in stock are traditional desktops are 0.6
The computers in stock are all-in-one touch screen machines are 0.1
Now the probability are
Probability that the computer is an all-in-one machine = Probability that the computers in stock are all-in-one touch screen machines / total computers in the stock.
Substitute the values in it then
Probability that the computer is an all-in-one machine = 0.1 / ( 0.3 + 0.6 + 0.1)
Probability that the computer is an all-in-one machine = 0.1 / 1
Probability that the computer is an all-in-one machine = 0.1.
So, The probability that the computer is an all-in-one machine is 10%.
