*) Since, here the card is replaced after 1st draw. So, events are independent.
Event A: there are 4 kings in 52 card deck.
So, the probability of draw 1 king is p(A)=4/52=1/13.
Event B: there are 4 ace in 52 card deck.
So, the probability of draw 1 ace is P(B)=4/52=1/13.
Since events A,B are independent, so P(A and B)=P(A).P(B)=(1/13).(1/13)=1/169=0.00592
**)Two die are rolled.
Event A: double are rolled.so, it contains (1,1), (2,2),(3,3),(4,4),(5,5),(6,6).
Event B: 5 is rolled in first dice. So, it contain (5,1),(5,2),(5,3),(5,4),(5,5),(5,6).
Here, (5,5) is common in both events. So the events are overlapping.
Determine whether the events A and B are independent. Find the probability of event {A and...
Decide whether events A and B are overlapping or non-overlapping. Two die are rolled. Event A: doubles are rolled Event B: 5 is rolled on first dice A. Non-overlapping B. Overlapping

2. Determine whether the following events are over- lapping or non-overlapping and find the probabil- ity. a. Rolling either a 3, a 4, or a 5 on a single die. b. Selecting either a woman or an American when you select a person at random from a group of 20 English women, 25 English men, 25 American women, and 20 American men. c. Drawing either an ace or a king from a stan- dard deck of 52 cards.
Find the indicated probability. Round your answer to 6 decimal places when necessary. You are dealt two cards successively (without replacement) from a shuffled deck of 52 playing cards.

Prisha has a standard deck of 52 playing cards. The deck contains 4 suits (hearts, diamonds, clubs, and spades), and each suit contains 13 cards labeled 2 through 10, as well as jack, queen, king, and ace. Four friends are trying to determine some probabilities related to drawing cards from the deck. Two cards will be randomly drawn from the deck, and after the first card is drawn, it is not replaced before the second card is drawn. Consider the...
Determine whether the events A and B are independent. A balanced die is rolled twice. Event A: The sum of the two rolls is 6 Event B: The first roll comes up 2 A. False B. True
3. You have a standard deck of 52 playing cards. There are two colors (black and red) and four suits (spades are black, clubs are black, hearts are red, and diamonds are red). Each suit has 13 cards, in which there is an ace, numbered cards from 2 to 10, and three face cards (jack, queen, and king) a. You randomly draw and then replace a card. What's the probability it's an ace? What's the probability it's the 4 of...
