Step-by-step explanation:
a) 6/36 = 1/6
b) 9/36 = 1/4
c) 9/36 = 1/4
d) 18/36 = 1/2
e) 9/36 = 1/4
Answer:
a)1/6
B)1/4
C)1/4
D)1/2
e)1/4
Step-by-step explanation:
Total outcomes are:36
a) Favourable outcomes of getting doublets:(1,1),(2,2),(3,3),(4,4),(5,5) and (6,6)
Favourable outcomes=6
Probability=Favourable outcomes/Total outcomes
Probability of getting doublets =6/36=1/6
B) both even numbers:(2,2),(2,4),(2,6),(4,2),(4,4),(4,6),(6,2),(6,4),(6,6)
Favourable outcomes=9
Probability=Favourable outcomes/Total outcomes
Probability of getting even numbers = 9/36=1/4
C) Both prime numbers:
(2,3),(2,5),(3,2),(3,5),(5,2),(5,3),(2,2),(3,3),(5,5)
Favourable outcomes=9
Probability=Favourable outcomes/Total outcomes
Probability of getting prime numbers = 9/36=1/4
D) one even one odd:(1,2),(1,4),(1,6),(2,1),(2,3),(2,5),(3,2),(3,4),(3,6),(4,1),(4,3),(4,5),(5,2),(5,4),(5,6),(6,1),(6,3),(6,5)
Favourable outcomes=18
Probability=Favourable outcomes/Total outcomes
Probability of getting one even one odd numbers = 18/36=1/2
e) Both odd numbers: (1,1),(1,3),(1,5),(3,1),(3,3),(3,5),(5,1),(5,3),(5,5)
Favourable outcomes=9
Probability=Favourable outcomes/Total outcomes
Probability of getting Both odd numbers numbers = 9/36=1/4
