Answer:

6/25

Explanation:

let Bk = event that Black king is picked at random

let Bk = event that Black king is picked at randomlet Q = event that Queen is picked at random

let Bk = event that Black king is picked at randomlet Q = event that Queen is picked at randomP(Bk V Q) = P(Bk) + P(Q) - P(Bk /\ Q)

since only card is taken the event P(Bk /\ Q) has value 0

since only card is taken the event P(Bk /\ Q) has value 0so P(Bk) + P(Q) = 2/52 + 4/52

since only card is taken the event P(Bk /\ Q) has value 0so P(Bk) + P(Q) = 2/52 + 4/52= 6/52
