1. First, it is necessary to determine the probability of getting a consonant of a vowel, by taking into account the probabilities shown on the diagram:
The vowels are E and A, and the sum of their probabilities is:
180/360 + 10/360 = 190/360 = 0.527
The consonants are D, B, F, and C, and the sum of their probabilities is:
90/360 + 20/360 + 40/360 + 20/360 = 170/360 = 0.472
Hence, it is more likely to hit a vowel
2. For the panel C or B, you have:
20/360 + 20/360 = 0.111
The probability is 0.111
3. The probability for each letter is:
E: 180/360 = 1/2
D: 90/360 = 1/4
C: 20/360 = 1/18
F: 40/360 = 1/9
B: 20/360 = 1/18
A: 10/360 = 1/36
Hence, panels C, F, B and A have a probability less than 1/6.
