Question

15 POINTS! PLEASE HELP! BRAINLIEST!

Answer 1

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%

Correct choice is D

Answer 2

Answer:

option D

Step-by-step explanation:

Total sample space

                               =  $2^{15}$

Number of ways 6 heads can emerge in 15 flips

                                                                          = $15C_6$  

Probability:

               $=\frac{15C_6}{2^{15}}$ $= 0.1527$

Probability to the nearest percent : 15.3%
