Question

14. A coin is tossed three times. What is the probability of tossing exactly two heads? a. 1 b. 5 c. 3 d. 1 2 3 3 15. When two cards are drawn from a standard deck, what is the probability of drawing a face car an ace? a. 3 b. 2 c. 5 d. 4 13 13 13 13 Part A: True/False Indicate whether the statement is true or false. 1. The probability of an event is between 0 and 1. 2. The sum of the probabilities of the outcomes in a sample space is between 0 and 1. If the probability of an event occurring is p, the odds against the event occurring are p:1- p. POXI P(X and ) If event X is dependent on event Y, then P() An event and its complement are mutually exclusive.

PLEASE ANSWER EVERY SINGLE ONE

Answer 1

14. correct answer: Option (C) 3/8
since coin is tossed 3 times so n = 3
and p = 1/2
P(X=two heads) = 3C2 / 2^3 = 3/8

True / False:

1. The probability of an even is between 0 and 1 --- True

2. false
since Sum of the probabilities of the outcomes in the sample space is 1

3. false

since odds againt: 1-p : p

4. True

5. true
