Answer:

Probability = 0.0244

Explanation:

Probability that Junior Non Physics Major & then a Freshman Non Physics Major are chosen:

Prob (Jr No-Ph Mjr)  = Jr No-Ph Mjr / Total

= 18 / 82 = 0.2195

Prob (Fr No-Ph Mjr) = Fr No-Ph Mjr / Total (remaining)

= 9 / 81 = 0.1111

Prob [ Jr No-Ph Mjr & Fr  No-Ph Mjr ] = 0.2195 x 0.1111 = 0.02439

≈  0.0244
