Respuesta :

Using the probability concept, the correct option regarding who is more likely to brush both in the morning and in the evening is:

B. Arabella. She has a 0.64 probability of brushing both times.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Considering that the events are independent, we just multiply the probabilities, hence the probability of each brushing both times is given as follows:

  • Braxton: 0.85 x 0.72 = 0.612.
  • Arabella: 0.79 x 0.81 = 0.64.

Hence statement B is correct, as 0.64 > 0.612.
