Question

# Domain of f(x) = log_{10}(log_{10}(1 + x^{3})) is -

- [0, )
- R
- R
^{+}
- None of these

^{+}## The correct answer is: R^{+}

### log_{10}

(1 + x^{3}) > 0 Take antilog

1+ x^{3} > 1 x^{3} > 0 x > 0

x (0, ) or x R^{+}

### If A and B are two events such that and then A and B are

As and

P(B)=P (AUB)- P(A) +P (A ∩ B) =

As P(A). P(B)=

So, A and B are independent events.

P(B)=P (AUB)- P(A) +P (A ∩ B) =

As P(A). P(B)=

So, A and B are independent events.

### If A and B are two events such that and then A and B are

Maths-General

As and

P(B)=P (AUB)- P(A) +P (A ∩ B) =

As P(A). P(B)=

So, A and B are independent events.

P(B)=P (AUB)- P(A) +P (A ∩ B) =

As P(A). P(B)=

So, A and B are independent events.
