Answer:
Step-by-step explanation:
Given: Let A be the event that the first die lands on 2 and B be the event that the second die lands on 2.
To find:
P(A), the probability that the first die lands on 2
P(B), the probability that the second die lands on 2
P(A and B): the probability that the first die lands on 2 and the second die lands on 2
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favourable outcomes/total number of outcomes
Sample space =
Total number of outcomes = 6
For P(A):
Number of favourable outcomes = 1
So,
For P(B):
Number of favourable outcomes = 1
So,
P(A and B) =
Yes, A and B are independent events as happening of each of the event does not depend on the other.
