• the variance of the event A
• the distribution of the event A
• the correlation of the event A
• the probability of the event A

A group of people were asked if statistics teachers know the true meaning of life. 462 responded "Yes", and 480 responded "No". Find the probability that if a person is chosen at random, the person believes statistics teachers know the true meaning of life. Probability = (Round to 4 decimal places)

Question 7 1 pt 0 1 2 9 0 Details As shown above, a classic deck of cards is made up of 52 cards, 26 are black, 26 are red. Each color is split into two suits of 13 cards each (clubs and spades are black and hearts and diamonds are red). Each suit is split into 13 individual cards (Ace, 2-10, Jack, Queen, and King). If you select a card at random, what is the probability of getting: (Round to 4 decimal places where possible) a) An 8 of Diamonds? b) A Club or Spade? () A number smaller than 2 (counting the ace as a 1)
