You flip a fair coin and pick one card out of a hat containing 20 cards numbered 1 to 20. What is the probability of getting heads on the coin and a number greater than 15 from the hat? Write your answer as a fraction.

Answer :

Final answer:

In mathematics related to probability, the chance of flipping a head on a fair coin and picking a card greater than 15 from a hat containing 20 cards numbered 1-20 is 1/8. This result comes from multiplying the individual probabilities of each event.

Explanation:

The subject matter of your question pertains to the field of probability in mathematics. The probability in question involves two separate events: flipping a heads on a coin (a fair one, meaning it has two equally likely outcomes: heads or tails), and drawing a card numbered higher than 15 from a hat that contains cards numbered 1 through 20. We calculate the probability of both these events happening simultaneously by multiplying the probabilities of each individual event.

  • Flipping a heads: As you've learned from your text, the probability of flipping a heads on a fair coin is 0.5 (or 1/2 in fraction form), because there exist two equally likely outcomes (heads or tails).
  • Drawing a card numbered more than 15: There are 20 cards, out of which 5 cards (16, 17, 18, 19, 20) are numbered higher than 15. Hence, the probability of drawing a card numbered more than 15 is 5 out of 20, or 1/4 in simplified form.

To find the probability that both these events occur simultaneously, we simply multiply these two probabilities together. That's (1/2) * (1/4) = 1/8. So the probability that you flip a heads and draw a card numbered greater than 15 is 1/8.
