A computer producing factory has only two plants T1 and T2 produces 20% and plant T2 produces 80% of the total computers produced. 7% of the computers produced in the factory turn out to be defective. It is known that P (computer turns out to be defective given that it is produced in plant T1 10P(computer turns out to be defective given that it is produced in plant T2 ). A computer produced in the factory is randomly selected and it does not turn out to be defective. Then the probability that it is produced in plant T2 is

#### Solution

NIMCET PYQ
A and B play a game where each is asked to select a number from 1 to 25. If the two number match, both of them win a prize. The probability that they will not win a prize in a single trial is :

NIMCET Previous Year PYQNIMCET NIMCET 2018 PYQ

#### Solution

The total number of ways in which numbers can be choosed =25 x 25=625  The number of ways in which either players can choose same numbers = 25
Probability that they win a prize = 25/625 = 1/25
Thus, the probability that they will not win a prize in a single trial = 1 - 1/25 = 24/25

NIMCET PYQ
A and B are independent witness in a case. The chance that A speaks truth is x and B speaks truth is y. If A and B agree on certain statement, the probability that the statement is true is

NIMCET Previous Year PYQNIMCET NIMCET 2017 PYQ

#### Solution

P(A speaks truth) = x
P(B speaks truth) = y
Since, both A and B agree on certain  statement.
Hence, Total Probability =P(A)P(B)+P(A')P(B')
=xy  + (1-x)(1-y)
If statement is true then it means both A and B speaks truth.

Probability of winning a prize = $\frac{1}{25}$​
Thus, probability of not winning = $1-\frac{1}{25}=\frac{24}{25}$​

A computer producing factory has only two plants $T_1$ and $T_2$. Plant $T_1$ produces 20% and plant $T_2$ produces 80% of total computers produced. 7% of computers produced in the factory turn out to be defective. It is known that P (computer turns out to be defective given that it is produced in plant $T_1$) = 10P (computer turns out to be defective given that it is produced in plant $T_2$). where P(E) denotes the probability of an event E. A computer produced in the factory is randomly selected and it does not turn out to be defective. Then the probability that it is produced in plant $T_2$ is
