Answer:
Step-by-step explanation:
The probability density function is :
With 0 < x < 3
To be a valid probability density function :
Where a < x < b
And also
f(x) ≥ 0 for a < x < b
Applying this to the probability density function of the exercise :
We can verify by replacing ''c'' in the original probability density function and integrating :
Also, f(x) ≥ 0 for 0 < x < 3

Answer:
Probability=
Step-by-step explanation:
As it is given that
Probability of toy A is defective is =P(A) =
Probability of toy b is defective if A is defective = P (B)=
WE have to find the P(A n B)
By the law of Probability
P(A n B) = P (A).P(B)
putting the values given to us
P(AnB)= *
Probability=
