Answer:

- 5

Step-by-step explanation:

let the number be n then 5 times the sum of n and - 1 is 5(n - 1), thus

5(n - 1) = 6n ← distribute left side

5n - 5 = 6n ( subtract 5n from both sides )

- 5 = n

Thus the number is - 5

The number of throws that the player make X follows binomial distribution.

The probability that the player makes x throws out of eleven throws is

$P(X=x)=C(x,11)0.5^x(0.5)^{11-x}=C(x,11)0.5^{11}$

The probability that the player makes at most nine out of eleven free throws

$\sum_{x=0}^9C(x,11)0.5^{11}=1-\sum_{x=10}^{11}C(x,11)0.5^{11}\\ =1-C(10,11)0.5^{11}-C(11,11)0.5^{11}=1-\frac{12}{2^{11}} \\ =1-\frac{3}{512} =\frac{509}{512}$

Correct choice is (B).
