The document discusses probability and contains 4 objectives: 1) The probability of a head or tail in a fair coin toss. 2) The probability of having 3 boys and 1 girl in a 4-child family is 1 in 4. 3) The probability of drawing a heart from a standard deck is 13/52 and drawing an ace is 4/52. 4) The probability of rain is 30% so not raining is 70%, and the probability that at least 2 people in a group of 15 have the same birthday is over 50%.

8. OBJECTIVE 2

10. Calculate the probability that in a 4-child family there are 3 boys and 1 girl. Assume equally likely outcomes.

11. Consider the experiment of drawing a card from a standard 52 card deck of playing cards (ace through king, four suits). Let E represent the event “draw a heart” and let F represent the event “draw an ace”.
