Mark(s): 1
Suppose in a box there are 25 red 35 blue 45 yellow 75
getting Bred 4 blue 5 yellow, 10 green balls?​

Answer 1

Answer:

then it must be a rubiks cube

Step-by-step explanation:

Answer 2

Therefore the total number of getting 3 red, 4 blue 5 yellow, and 10 green balls from a box containing 25 red, 35 blue, 45 yellow, and  75 green in a box ²⁵C₃ × ³⁵C₄ × ⁴⁵C₅ ×  ⁷⁵C₁₀ ways.

Given:

There are 25 red, 35 blue, 45 yellow, and  75 green in a box.

To Find:

The total number of getting 3 red, 4 blue 5 yellow, and 10 green balls from a box containing 25 red, 35 blue, 45 yellow, and  75 green in a box.

Solution:

The given question can be solved very easily as shown below.

⇒ The number of ways of getting 3 red balls from 25 red balls = ²⁵C₃ = ( 25 × 24 × 23 )/( 3 × 2 × 1) = 25 × 4 × 23 = 2300 ways

⇒ The number of ways of getting 4 blue balls from 35 blue balls = ³⁵C₄ = ( 35×34×33×32 )/(4×3×2×1) = (35×17×11×8) = 52360 ways

⇒ The number of ways of getting 5 yellow balls from 45 yellow balls = ⁴⁵C₅ ways

⇒ The number of ways of getting 10 green balls from 75 green balls = ⁷⁵C₁₀ ways

The total number of ways = ²⁵C₃ × ³⁵C₄ × ⁴⁵C₅ ×  ⁷⁵C₁₀ ways

Therefore the total number of getting 3 red, 4 blue 5 yellow, and 10 green balls from a box containing 25 red, 35 blue, 45 yellow, and  75 green in a box ²⁵C₃ × ³⁵C₄ × ⁴⁵C₅ ×  ⁷⁵C₁₀ ways.
