These are shown in the table. Braxton Arabella 0.79 0.85 Probability of brushing In moming Probability of brushing In evening 0.81 0.72 Who is more likely to brush both morning and evening? Assume all events are independent. A. Arabella. She has a 0.72 probability of brushing both times B Braxton. He has a 0.64 probability of brushing both times,​

Step-by-step explanation:

Answer 2

B Braxton. He has a 0.64 probability of brushing both times.

What is probability?

Probability is a branch of mathematics that deals with the occurrence of a random event.

Calculation:-

probability of brushing in the morning:-

 Braxton  =  0.79

  Arabella = 0.85

   

probability of brushing in the evening:-

 Braxton  =  0.81

  Arabella = 0.72

Total probability of brushing Braxton =  0.79*0.85

                                                              = 0.632

Total probability of brushing Arabella = 0.85* 0.72

                                                               = 0.612
