Rectangle area is 3 x 2 = 6 m². With diameter 1 m, circle radius is 0.5 m, so circle area is π x (0.5)² = π / 4 m². The landing probability is (π / 4) / 6 = ...

For two dice, maximum sum is 12. An event with probability 0 is getting a sum of 13. An outcome or event with probability 1 is getting a sum between 2 and 12.
(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) ...
With replacement, total pens = 9. Outcomes for colors are RR, RB, RG, BR, BB, BG, GR, GB, GG. The probability of both picking the same color is P(RR) + P(BB) + P(GG) = 9/81 + 16/81 + 4/81 = ...
For green sweets, probability is 8 / 30 = 4 / 15 (or approximately 0.267). For yellow sweets, sample probability is 7 / 30. In 600 sweets, the expected yellow sweets count is (7 / 30) x 600 = 140.
