The Venn diagram has regions: 6 (outside all), 10 (Snowboard only), 7 (Ice Skate only), 13 (Ski only), 4 (Ice Skate and Snowboard only), 2 (Ice Skate and Ski only), 8 (Snowboard and Ski only), 3 (all three).

Step2: Sum all regions

Add all values: \( 6 + 10 + 7 + 13 + 4 + 2 + 8 + 3 \)

Step3: Calculate the sum

\( 6 + 10 = 16 \); \( 16 + 7 = 23 \); \( 23 + 13 = 36 \); \( 36 + 4 = 40 \); \( 40 + 2 = 42 \); \( 42 + 8 = 50 \); \( 50 + 3 = 53 \)

Answer:

53
