A bag contains 7 red marbles, 5 yellow marbles, 6 blue marbles, 4 green marbles, and 3 orange marbles. What is the probability o

baherus [9]

The probability of randomly selecting a yellow marble out of the bag is $\frac{1}{5}$

Step-by-step explanation:

A bag contains:

7 red marbles
5 yellow marbles
6 blue marbles
4 green marbles
3 orange marbles

We need to find the probability of randomly selecting a yellow marble out of the bag

Probability is the ratio of number of favorable outcomes to the total number of possible outcomes P(A) = $\frac{n(A)}{n(outcoms)}$

∵ A bag contains 7 red marbles, 5 yellow marbles, 6 blue

marbles, 4 green marbles, and 3 orange marbles

- Add all the color to find the number of total marbles

∴ n(all) = 7 + 5 + 6 + 4 + 3 = 25

∵ There are 5 yellow marbles

∵ P(yellow) = $\frac{n(yellow)}{n(all)}$

∴ P(yellow) = $\frac{5}{25}$

- Divide up and down by 5 to simplify the fraction

∴ P(yellow) = $\frac{1}{5}$

The probability of randomly selecting a yellow marble out of the bag is $\frac{1}{5}$

How can we factorise the expression: 2x^6+17x^3+8?

LekaFEV [45]

Answer:

$(a + 2)( {a}^{2} - 2a + 4 )(2 {x}^{ 3} + 1)$

Step-by-step explanation:

$2x^6+17x^3+8 \\ = 2x^6+16x^3 + {x}^{3} +8 \\ = 2{x}^{3} ( {x}^{3} + 8) + 1( {x}^{3} + 8) \\ = ( {x}^{3} + 8)(2 {x}^{ 3} + 1) \\ = ( {x}^{3} + {2}^{3} )(2 {x}^{ 3} + 1) \\ = (a + 2)( {a}^{2} - 2a + {2}^{2} )(2 {x}^{ 3} + 1) \\ = (a + 2)( {a}^{2} - 2a + 4 )(2 {x}^{ 3} + 1) \\$
