What do you mean by dimensions of any geometrical shapes?

Chandan replied | 22/11/2016

Two geometric shapes that share the same basic shape are called "similar to each other." If both shapes are the same size, they are called "congruent." Geometric shapes can be two-dimensional or flat. They can be three-dimensional, meaning they possess depth and volume.

Two cubes each of volume 64 cubic cm are joined end to end. Find the total surface area of the resulting cuboid?

Sreedevi replied | 02/12/2016

T.S.A of cuboid = 2 (lb+bh+lh);Given volume of the cube = 64 cubic cm.
From this we can find the length of the side of the cube by taking the cube root of 64 and it is equal to 4.
Now we have length of the cube = breadth of the cube = height of the cube = 4cm.
On joining 2 such cubes, we get length of the cuboid = 4+4 =8 cm; breadth and height remain same as we are...  more»

On joining 2 such cubes, we get length of the cuboid = 4+4 =8 cm; breadth and height remain same as we are joining the two cubes side by side.
On substituting the values, we get T.S.A = 160 square cm «less

Can the experimental probability of an event be greater than 1? Justify your answer?

Sreedevi replied | 02/12/2016

No, because the number of successes and failures should be equal to 1.

Sreedevi replied | 02/12/2016

No, because the number of successes and failures should be equal to 1.
The probability of an event will not be less than 0. This is because 0 is impossible (sure that something will not happen). The probability of an event will not be more than 1. This is because 1 is certain that something will happen.

Find the probability of getting a number less than 5 in a single row of a die?

Sreedevi replied | 02/12/2016

In the single throw of a die, the sample space n(S) = 6; let 'E' be the event of getting '5'. n(E) = 1; P(E) = n(E) /n(S); P(E) = 1/6.

One card is drawn from a well shuffled deck of 52 cards. Find the probability of drawing an ace?

Sreedevi replied | 02/12/2016

There will be 4 aces (Event E) that belongs to 4 different types say hearts, clubs, diamonds and spades. The probability of getting an ace of 52 cards (sample space = 52) is given by the ratio of favourable events to sample space.
P(E) = n(E) / n(S); P(E) = 4/52; P(E) = 1/4.

Two dice are thrown. What is the probability of obtaining a total of 10 or 11?

Mamata replied | 25/11/2016

Sample space = {(1,1), (1,2,), ........, (5,6), (6,1), (6,6)}
Number of sample space or cardinality of S = |s|= 36
Let A be the event of getting total of 10 or 11
A={(5,5),(5,6),(4,6),(6,4),(6,5)}.
|A|=5.
P(A)= |A|/|S|= 5 / 36.

If angle sin A = 1/2, then the value of cot A?

T Raghavender replied | 26/11/2016

SinA=1/2. =>A=30 degrees, cotA = cot30 = root 3.

Sarvajeet replied | 02/12/2016

sin A = 1/2, cos A = square root 3 /2.
cot A = square root 3.

What is the value of (tan 1 degree tan 2 degree tan 3 degreeâ€¦...tan 89 degree)?

Suyash replied | 19/11/2016

Here,
tan 1Â°Ã— tan 89Â° = tan 1Â° Ã— cot 1 Â° = 1
& Similarly,
tan 2Â°Ã— tan 88Â° = 1 as so on.
So the value of,
tan1Â° Ã— tan2Â° Ã— ... tan 89Â° = tan 45Â° = 1

Define set?

Chandan replied | 22/11/2016

A collection of "things" (objects or numbers, etc).
Each member is called an element of the set.
There should be only one of each member (all members are unique).
Here is a set of clothing items.
Another Example: {1,2,3,4} is the set of counting numbers less than 5
