Question
A die is thrown, then find the probability of the following events:
A is an event: getting a perfect square.
B is an event: getting a prime number.
Solution
Sample Space S ≡ {1, 2, 3, 4, 5, 6}
∴ n(s) = 6
A ≡ { Event getting a perfect square}
≡ { 1, 4}
n(A) = 2
∴`"P"("A") = ("n"("A"))/("n"("s"))=2/6=1/3`
B≡ { Event getting a prime number}
B ≡ { 2, 3, 5}
n(B) = 3
∴`"p"("B") = ("n"("B"))/("n"("s"))=3/6 = 1/2`
