1) Probability of randomly selecting a diamond or club =
2)Probability of randomly selecting a diamond or club or heart =
3) P(selecting a five or club) =
Step-by-step explanation:
Total cards in the deck = 52
Noe Let E : favorable Event
So,
1 ) Probability of randomly selecting a diamond or club
Here the favorable event is picking a club or diamond
hence, favorable outcomes = Number of club and diamond
= 13 + 13 = 26
⇒P(selecting a diamond or club) =
2) Probability of randomly selecting a diamond or club or heart
Here the favorable event is picking a diamond and club and heart.
hence, favorable outcomes = Number of clubs + diamond + heart
= 13 + 13 + 13 = 39
⇒P(selecting a diamond or club or heart) =
3 )Probability of randomly selecting a five or club.
Here the favorable event is selecting a five or club.
hence, favorable outcomes = Number of 5 in a deck + Number of clubs
= 3 + 13 = 16
⇒P(selecting a five or club) =
