Answer:

3/8

Step-by-step explanation:

Looking at the bottom row, there are 8 possible outcomes

HHH, HHT, HTH, HTT, THH, THT, TTH, TTT

There are 3 that have exactly 2 heads HHT, HTH, THH,

That means the probability is

P( exactly 2 heads) = number outcomes with exactly 2 heads/total outcomes

=3/8

abruzzese [7]

If z ⁷ = 128i, then there are 7 complex numbers z that satisfy this equation.

$z^7 = 128i = 2^7i = 2^7e^{i\frac\pi2}$

$\implies z=\sqrt[7]{2^7} e^{i\frac17\left(\frac\pi2+2n\pi\right)}$

(where n = 0, 1, 2, …, 6)

$\implies z = 2 e^{i\left(\frac\pi{14}+\frac{2n\pi}7\right)}$

$\displaystyle\implies z = 2 \left(\cos\left(\frac\pi{14}+\frac{2n\pi}7\right)+i\sin\left(\frac\pi{14}+\frac{2n\pi}7\right)\right)$
