To Find:
Find the probability of one of the pens is drawn is green
Solution:
Probability:
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
It is given by = favorable events / Possible events
Favorable events= number of green pens= 2
Total events= total pens= 2+3+2=7
probability of one of the pens is drawn is green
=(number of green pens/total pens)
=2/7
Hence the probability of one of the pens is drawn is green is 2/7.
