Answer:

  • D.  15.3%

Step-by-step explanation:

Total number of outcomes:

  • 2¹⁵ =  32768

Number of combinations of getting 6 heads:

  • 15C6 = 15!/6!(15-6)! = 5005

Required probability is:

  • P(6 heads out of 15 flips) = 5005/32768 = 0.1527... ≈ 15.3%

Answer:

option D

Step-by-step explanation:

Total sample space

                               =  [tex]2^{15}[/tex]

Number of ways 6 heads can emerge in 15 flips

                                                                          = [tex]15C_6[/tex]  

Probability:

               [tex]=\frac{15C_6}{2^{15}}[/tex] [tex]= 0.1527[/tex]

Probability to the nearest percent : 15.3%
