Question

From a regular deck of cards, select a card, look at it and remember what it is or write it down, replace it into the same deck, shuffle the deck at least 7 times, then select a 24 card. Find the probability that both cards are HEARTS From a regular deck of cards, select a card, look at it and remember what it is or write it down, replace it into the same deck, shuffle the deck at least 7 times, then select a card. Find the probability that both cards are RED. 25 26 10 8 Spin this wheel and record the number that has the arrow pointing to it: spin the wheel again and record the second number; find the probability that both numbers are ODD Toss a regular die one time, record the number showing:; then pick up the same die and toss it again. Find the probability that the first number is even and the second number is ALSO EVEN. 27 Toss three regular dice one time, record the total; Find the probability that the dice will show triples 28 ( triples means all dice have the same number showing)

Explanation / Answer

24) P(HEARTS) = 1/4

P(both are HEARTS) = 1/4 x 1/4

= 1/16

= 0.0625

25) P(RED) = 1/2

P(both are RED) = 1/2 x 1/2

= 0.25

26) Total number = 11

Number of odd nubers = 5

P(odd number) = 5/11

P(both are odd numbers) = 5/11 x 5/11

= 25/121

27) P(first number is even) = 1/2

P9second number is even) = 1/2

P(both numbers are even) = 1/2 x 1/2

= 0.25

28) P(showing tripples) = P(second and third die showing the same that was shown by the first)

= 1 x 1/6 x 1/6

= 1/36
