If you multiply by 6, 6/v x 6 = 36/v, that’s why it don’t work.

Answer:
-9=6/v
-9v=6
v=-6/9

Nuetrik [128]

Answer:

The answer is "0.0547".

Step-by-step explanation:

$P(Correct) = 0.50\\\\n = 10\\\\x = 8$

Using the binomial distribution:

$\to P(x,n) = n_{C}_x \times p^x \times (1-p)^{(n-1)}\\\\\to P(x \geq 8) = 1 - P( \leq 7)$

Calculating the excel formula:

$=BINOM.DIST(7,10,0.50,TRUE)$

$\to P(x \geq 8) = 1 - 0.9453\\\\ \to P(x \geq 8) = 0.0547$
