• The middle term 'educated' is not properly distributed
• No definite conclusion follows

Explanation

• The 'some brave people who are decorated' may or may not include soldiers
• This is an undistributed middle term situation
• The conclusion cannot be determined

Explanation

• Possible outcomes: HH, HT, TH, TT (4 total)
• Only TT has no heads
• Probability = 1/4

Explanation

Explanation

• Whales are entirely within the mammal category
• Since no fish are mammals, and whales are mammals, no whale can be a fish

Explanation

• A is a subset of B, and B is a subset of C, so A is a subset of C
• Since no C is D, and A is entirely within C, no A can be D

Explanation

• Total outcomes = 8
• Outcomes with at least 2 heads: HHH, HHT, HTH, THH (4 outcomes)
• Probability = 4/8 = 1/2

Explanation

• Some flowers fall in the 'red' category
• Since all red things are beautiful, those flowers must be beautiful
• Hence, some flowers are beautiful

Explanation

• All teachers fall into the 'kind' category
• Since no kind person is cruel, no teacher (being kind) can be cruel

Explanation

• Total outcomes = 2^4 = 16
• Number of ways to get exactly 2 heads = C(4,2) = 6
• Probability = 6/16 = 3/8
