Answer:

b. No

Step-by-step explanation:

Represent

  • Square Pizza with S
  • Soft Drink with D

Such that

P(S) = 49\%

P(D) = 71\%

P(S\ and\ D) = 38\%

Required

Determine if events S and D are independent

Two events S and D are independent if:

P(S\ and\ D) = P(S) * P(D)

Substitute values for P(S) and P(D)

P(S\ and\ D) = 49\% * 71\%

Convert to decimals

P(S\ and\ D) = 0.49 * 0.71

P(S\ and\ D) = 0.3479

Convert to percentage

P(S\ and\ D) = 0.3479 * 100\%

P(S\ and\ D) = 34.79\%

The calculated P(S and D) is not equal to 38%

Hence, the events are not independent.
