Question

Find the indicated probability 1) If you flip a coin three times, the possible outcomes are HHH, HHT, HTH, HTT, THH, THT, TTH, TTT a) What is the probability of getting at least one head? b) What is the probability of getting at least two tails? c) What is the probability of getting all heads? 2) f two balanced die are rolled, the possible outcomes can be represented as follows. a) Determine the probability that the sum of the dice is 10. b) Determine the probability that the sum of the dice is more than 10 c) Determine the probability that the sum of the dice is 3 or 12

Explanation / Answer

Q1

a) P(atleast 1 Head) = 7/8 = 0.875

b) P(atleast two tails) = 4/8 = 1/2 = 0.5

c) P(all heads) = 1/8 = 0.125

Q 2

a) P(sum is 10) = 3/36 = 0.0833

b) P(sum is more than 10) = 3/36 =0.0833

c) P( 3 or 12) = (2+1)/36 = 3/36 = 0.0833
