I get 65.94

Step-by-step explanation: 6 15 19 11

3.14 (a²+ab) when a equals 3 and b equals 4

3.14 (3²+3b) when a equals 3 and b equals 4

3.14 (a²+ab) when a equals 3 and b equals 4

3.14 (3²+3×4) when a equals 3 and b equals 4

3.14 (3²+3×4)

3.14 (9+12)

3.14 (21)

3.14 × 21 = 62.8 + 3.14 = 65.94

Total number of beads 7+10+3=20. We are looking at the combination of 20 events. Applying the probability formula $p= \frac{m}{n}$ , the total number of possible outcomes is $C _{20}^{2}$ and the possible outcomes is $C_{10} ^{2}$ . Then, the probability is $p= \frac{C_{10} ^{2} }{C_{20} ^{2} } = \frac{9}{38} = 0.236842$
