A game of telephone is played with 5 students: Angela, Bob, Carlos, Dee, and Frank. That is, a teacher whispers a saying to Angela, who whispers it Bob, who whispers is to Carlos, who whispers it to Dee, who whispers it to Frank, and Frank announces what he thinks he heard. Angela understands the correct saying 80% of the time, Bob’s accuracy is 65%, Carlos 85%, Dee 70%, and Frank 75%. Given that the saying at the end does not match the saying from the teacher, what is the probability that Bob was inaccurate? g
