- $\frac{63}{64}$
- $\frac{57}{64}$
- $\frac{7}{64}$
- $\frac{37}{64}$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
$P(E) = \frac{2^6 - 1 - 6}{2^6} = \frac{64 -7}{64} = \frac{57}{64}$

- Water is flowing through a horizontal tube having cross-sectional areas of its two ends beings $A$ and $A$' such that the ratio $A/A$' is $5$. If the pressure difference of water between the two ends is $3 \times 10^5\, N m^{-2}$, the velocity of water with which it enters the tube will be (neglect gravity effects)

Bernauli Theorem
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. The principle is named after Daniel Bernoulli who published it in his book Hydrodynamica in 1738.
