Question

A bag contains 10 counters

6 of them are white
a counter is taken at random and not replaced
a second counter is taken out of the bag at random
calculate the probabillity that only one of the two counters is white? please help

Answer 1

44%

6/10 = 3/5

3/5 x 1/10 = 3/50

3/50 x 1/10 = 3/500

3/500 / 2/6 = 44/100
