44502 Good luck SAVE AND EXIT SAVE Question 1 (multiple choice) Phasma has to choose a day for a party. She decides to choose a random day in May. There are 31 days in May, and during the year she chooses, the first day in May is a Sunday Which formula should Phasma use to determine the probability that the day she chooses is either a weekend day (Saturday or Sunday) or a day between the 15th and the 31st of the month? O P(An B) P(A) P(B) o P(AU B) = P(A) + P(B) P(AU B) = P(A) + P(B)-P(An B) o P(A n B) = P(A) , p(BIA) n 2 (multiple answer)

Explanation / Answer

probability event A = day she chooses is a weekend day = P(A)

Probability of event B = day she chooses is between15th and 31st of the month = P(B)

Now it may happen that she chooses a day that can be weekend day and also between 15th and 31st of the month, so for that probability is P(A n B), since this day's probability has already chosen by in both event A and in event B, so we need to subtract this day one time

So,

P(AUB) = P(A) + P(B) - P(AnB)

Correct option is C.
