4 kartu AS dikocok kemudian diambil satu secara acak. berapakah peluang terambil di AS hati??

4 kartu as,
n(S) = 4
As = {As hati, As wajik, As keriting, As sekop}
n(As hati) = 1
Maka,
P(As hati) = n(As Hati)/n(S) = 1/4

Kartu dengan kesuluruhan : 4 AS
Kartu yang di inginkan : AS hati (cuman ada 1 diantara 4 kartu AS)

Jadi jawabannya 1/4
