Given :
Number of red balls = 3
Number of gree balls = 2
Number of blue balls = 1
Total balls = 6
Formula :
Probability = Number of favorable outcome/Total outcome
According to question, first ball pulled out is red.
So, probability of getting red ball again :
Total outcome = 5
Favorable outcome (red balls ) = 2
Probability = 2/5
= 2/5 or 0.40
Thus, probability of pullin a red ball again is 2/5 or 0.40.
