Two friends argue over who brushes their teeth more often. To settle the
argument, they keep track of the number of mornings and nights they brush
and calculate a probability. These are shown in the table.
Braxton
Arabella
0.72
0.82
Probability of brushing
in morning
Probability of brushing
In evening
0.85
0.79
Who is more likely to brush both morning and evening? Assume all events are
independent
A. Braxton. He has a 0.85 probability of brushing both times,
B. Arabella. She has a 0.65 probability of brushing both times.
