Question:
A fair die is tossed.
Find the probability of obtaining an even number
Answer:
sample space=(1,2,3,4,5,6)
number of favourable outcomes=3
Event A= (outcome is even)
= (2,4,6)
Total number of outcomes=6
Thus, P(even number)=3/6
=1/2
Question 2:
A drawer contains 10 identical handkerchiefs of which 2 are white, 5 are blue, and 3 are pink. A handkerchief is drawn at random. what is the probability that it is white or pink?
Answer:
total number of outcomes=10
P(the handkerchief is white or pink)=2+3/10
=5/10
=1/2
