Answer:
73% chance that they will be able to speak the same language
Step-by-step explanation:
The probability that both people speak english will be 0.8*0.8 since we must account for bilingual people.
The probability that the both speak spanish is 0.3+0.3.
To have the total probability that both speak the same language we simply sum both propabilities.
0.8²+0.3²=0.73
