Question

A bag contains4 white 5 red 6 blue balss three balss are drawn at random what is the propabikity that one ball is red

Answer 1

given total no.of red balls=5

total no.of outcomes =15

no.of favourable outcomes =5

we know probability =no.of favourable outcomes/total no.of outcomes
=5/15
=1/3

Answer 2

Total balls= 4+5+6

Probabilityy of 1 being red= (4+5+6)/100

=14/100

=7/50=7.14285%
