Question

a bag contains a white,6 black ,7 yellow amd 4 pink marbles ,what is the probability of getting a bkack marble when one marble is drawn randomly​

Answer 1

Step-by-step explanation:

Total Number Of Marbles=1+6+7+4=18

Total Number Of Black Marbles=6

So The Fractiona Between Total Number Of Marbles And Number Of Black Marbles Is=6/18

If We Simplify 6/18 We Get=1/3

Now To Calculate Probability We Need To Convert Fractions To Percentage.

So 1/3 In Percentage Is

$\frac{1 \times 100}{3 } = \frac{100}{3} = 33.33\%$

So The Probability Of Getting A Black Marble Out Of A White,6 Black,7 Yellow & 4 Pink Marble Is 33.33%.

Answer 2

Total Number Of Marbles = 1 + 6 + 7 + 4 = 18

Total Number Of Black Marbles = 6

So The Fraction Between Total Number Of Marbles And Number Of Black Marbles Is = 6/18

If We Simplify 6/18 We Get = 1/3

Now To Calculate Probability We Need To Convert Fractions To Percentage.

So 1/3 In Percentage Is

$\frac{1 \times 100}{3 } = \frac{100}{3} = 33.33\%$

So The Probability Of Getting A Black Marble Out Of A White , 6 Black , 7 Yellow & 4 Pink Marble Is 33.33% .
