So out of 100 girls the number of girls who prefer dodge is:18/56 ×100

  • Number of girls who prefer Dodge is: 32.143≈32

Probability of boys who prefer Dodge is: 17/46

So out of 100 boys the number of boys who prefer dodge is:17/46 ×100

  • Number of boys who prefer Dodge is: 36.956≈37

This means that the number of boys who prefer dodge are more than the number of girls who prefer dodge.

Hence, option: A is correct.

Probability of boys who prefer Ford is: 18/46

So out of 100 boys the number of boys who prefer ford is:18/46 ×100

  • Number of boys who prefer Ford is: 39.13≈39

This means that the number of girls who prefer ford are more than the number of boys who prefer ford.

Hence, option: C is incorrect.

D)

Probability of girls who prefer Chevrolet is: 13/56

So out of 100 girls the number of girls who prefer Chevrolet is:13/56 ×100

  • Number of girls who prefer Chevrolet is: 23.214≈23
