Question

a bag contains 10 white,4 red,6blue balls then the fraction of white balls is​

Answer 1

Step-by-step explanation:

ANALYSIS

Probability(Ball1 is Red) = ( 10/15 ).

Ball 1 is NOT replaced.1

There are now 9 Red balls in a total of 14 balls left as the Red ball has not been replaced.

Probability(Ball 2 is Red) = (9/14)

Therefore ProbabilityBoth Balls are Red) = ( 10/15 )*( 9/14 ) = ( 90/210 )

= ( 9/21 ) = ( 3/7 )

or 0.42857

or 42.857%

Answer 2

Given :

White balls - 10

Red balls - 4

Blue balls - 6

To find :

Fraction of white balls

=> Total no. of balls = 10 + 4 + 6 = 20

Fraction of white balls = No. of white balls/ Total no. of balls

= 10/20 = 1/2
