Probabilty question

Question

30 students participated in a survey. 9 students stated they took French, 14 students stated they took Spanish, and 7 students stated they took both. To the nearest two decimals, what is the probability of selecting a student that took either French or Spanish?

Answer 1

P(F) = 9/30

P(S) = 14/30

P(S&F) = 7/30

P(S v F) = P(F)+P(S)-P(S&F) = 9/30 + 14/30 - 7/30 = 16/30 = 8/15 = 0.5333....

= 0.53 rounded to 2 decimals = 53%. or 53.33% if you want 2 decimal places of a percentage.
