Answer 1

Around 83% 473/ 570

Explanation:

365 males + 108 females with brown hair = 473

Divide the number of outcomes desired by the total number of outcomes 473/570 = 0.829824....... = 82.98.....%

Answer 2

473/570

Explanation:

No. of male = 365

No. of female = 570-365 = 205

No. of male with brown hair = 260

No. of female with brown hair = 108

the probability that a person was male or had brown hair = 365/570+108/570 = 473/570 [ for or case we add probabilities]
