Answer:

The value of P(A and B)  is 1/10

Step-by-step explanation:

In case of independent events, the probability of one event doesn't depend on the probability of other events.

Therefore, for an independent events

P(A and B) = P(A) × P(B)

P(A and B) = 2/5  × 1/4

P(A and B) =2/20

P(A and B) =1/10

Therefore, the value of P(A and B)  is 1/10

Answer:

1/10 is the probability of A and B.

Step-by-step explanation:

Probability of independent events means probability of  occuring of one event does not affect the probability of occuring of oth event.

Given that

P(A) = 2/5   and P(B) = 1/4

The formula to find probability of A and B for independent events is:

P(A and B) = P(A)×P(B)

Putting given values in above formula, we have

P(A and B) = 2/5× 1/4

P(A and B) = 2/20

P(A and B) = 1/10 which is the answer.

Volume of a Cube Formula: V = a³

  • <em>a</em> is a side length

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em>V</em> = 270 cm³

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Substitute in variables [Volume of a Cube Formula]:                                     270 cm³ = a³
  2. [Equality Property] Cube root both sides:                                                        6.4633 cm = a
  3. Rewrite:                                                                                                              a = 6.4633 cm
  4. Round:                                                                                                                  a ≈ 6.5 cm

From a group of 7 men and 6 women, five persons are to be selected to form a committee so that at least 3 men are there in the c
Ivan

The total possibilities can be 756 ways.

<h3>What is combination?</h3>

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order. Combinations can be confused with permutations.

Given:

The number of ways in which we can select atleast 3 men in the committee are 756.

Number of men = 7

Number of women = 6

Number of people that should be selected in the committee = 5

Now,

N(M = 3) = 7C_3* 6C_2

=35*15

=525

N(M = 4) = 7C_4* 6C_1

=35*6

=210

N(M = 3) = 7C_5* 6C_0

=21*1

=21

So, total possibilities can be = 525 + 210 + 21 = 756 ways.
