For a biased die, the probabilities for different faces to turn up are

$Face :$	$1$	$2$	$3$	$4$	$5$	$6$
$P(F)$	$0.2$	$0.22$	$0.11$	$0.25$	$0.05$	$0.17$

The die is tossed and you are told that either face $4$ or face $5$ has turned up. The probability that it is face $4$ is

If A = {1, 2, 3}; B = {3, 4, 5}; C = {4, 6}, then $\text{A}\times(\text{B}\cap\text{C})=?$

At $x=\frac{5 \pi}{6}, f(x)=2 \sin 3 x+3 \cos 3 x$ is

$\int_{}^{} {{x^2}\sec {x^3}\;dx} = $

Let $f ( x )= x \cdot\left[\frac{ x }{2}\right],$ for $-10< x <10,$ where $[ t ]$ denotes the greatest integer function. Then the number of points of discontinuity of $f$ is equal to

${{{d^n}} \over {d{x^n}}}({e^{2x}} + {e^{ - 2x}}) = $

The points of discontinuity of the function $\text{f(x)}=\begin{cases}2\sqrt{\text{x}},&0\leq\text{x}\leq1\\4-2\text{x},&1<\text{x}<\frac{5}{2}\\2\text{x}-7,&\frac{5}{2}\leq\text{x}\leq4\end{cases}$ is (are):

$\text{x}=1,\text{x}=\frac{5}{2}$
$\text{x}=\frac{5}{2}$
$\text{x}=1,\frac{5}{2},4$
$\text{x}=0,4$
