The bag contains 3 distinct candies, giving a total of 3 possible outcomes. Since there is only 1 strawberry candy, the probability is 1 / 3 (approximately 0.333 or 33.3%).
(i) S = {HH, HT, TH, TT}, P(at least 1 head) = 3/4. (ii) S = {1, 2, …, 10}, P(even) = 5/10 = 1/2. (iii) S = {1, 2, 3, 4, 5, 6}, P(> 4) = 2/6 = 1/3. (iv) P(not red) ...
Experiments (ii), (iii) and (v) have equally likely outcomes due to symmetry and equal chance. Experiments (i) and (iv) are not equally likely because mechanical conditions bias car starting and blue marbles outnumber red ones.
